"Dr Oliver can submit a report, of course," replied Wilson. "I"m sure the magistrate will take it into account."
Harry was about to respond quite what he would have said, he hadn"t quite decided when they heard footsteps coming down the stairs. They could hear Rushton"s distinctive voice, then the front door opening and closing. The footsteps turned in the direction of the kitchen then stopped.
"This is something the family need to know," they heard Rushton say, in a voice that was low but firm. Then he came into the room, knocking on the door politely as he opened it. He was followed by DI Neasden and a female constable. Neasden didn"t look happy.
"Sorry to interrupt, Mrs Fletcher," said Rushton. "Need a word, if I may."
Alice seemed to be bracing herself for another blow. "OK," she said. "Do you need to see me alone?"
Rushton looked quickly round the table, avoiding Neasden"s eyes. "Oh, I think we"re all friends together," he said. ""Ow do, Hannah. You on your way out?"
"Have you found something?" asked Harry.
"I think so," replied Rushton. "What time"s your husband home, Mrs Fletcher?"
Alice seemed to have lost her ability to think quickly. She glanced at her watch, then at Harry. "He said he"d be a couple of hours," she said after a moment. She turned to the kitchen clock on the wall behind her. "A site inspection he couldn"t get out of. He should be back any time now."
"Good," said Rushton. "And you might want to get a locksmith up here. See if these locks can"t be changed."
"What is it?" asked Alice.
Rushton pulled out the chair Evi had just vacated and sat down. Behind him, DI Neasden, his lips pressed tightly together, leaned back against the tall kitchen cupboard. The constable remained by the door, softly closing it behind her.
"You remember we found some footprints in the garden last night," began Rushton. "Our forensics people took casts of them." He turned to the man behind him. "Have you got it, Jove?" he asked.
DI Neasden had been carrying a thin, blue plastic wallet. With obvious reluctance, he pulled a stiff sheet of A4 white paper from it and handed it to his boss. Rushton turned it to face Alice and Harry. It was a photograph of a footprint in mud.
"We know the prints must have been left in the garden late last night," said Rushton, "because of all the rain you had up here. If they"d been left earlier in the evening, they"d have been washed away. So we know at least one person apart from your children was out there round about the time the wall came down."
Hannah leaned forward to study the print.
"We took several casts of footprints last night," said Rushton, "and a whole load of photographs, but this one is the most clear." He turned to Harry. "You remember me mentioning that the constable who was first on the scene was a bright lad?"
Harry nodded.
"Brighter than I thought, it turns out," continued Rushton, "because he spotted this print, knew the rain would compromise it and put an upturned bucket over it until the crime team could get here. They were able to take some very good photographs and make a good cast."
"They"ve made a cast of this?" asked Alice. "What with plaster?"
"Dental stone, I believe," answered Rushton. "A very tough, durable sort of plaster." He pointed to the footprint. "This here"s probably a size seven, maybe an eight," he said. "Not the most helpful to have, frankly, because it could be a tall woman or a small-footed man. You"re a size four, I understand, Mrs F?"
Alice nodded. "And Gareth"s a-"
"A ten, yes, we know. We took casts of his prints as well. Matched them to the boots he was wearing when he went outside. These prints are quite different. Much cruder tread on them. Can you see?" Rushton ran his finger around the outline of the print.
Harry leaned forward to get a better look. Horizontal ridges ran across the print. From the shadows on the photograph they looked deep, the sort of ridges you might see on a boot made for walking through deep mud.
"Looks like a bog-standard wellington to me," he said. In the instep arch between sole and heel, he could just about make out an incomplete shape, maybe two-thirds of a gently rounded triangle. "Is that a manufacturer"s logo?" he asked.
"Yes, indeed," said Rushton. "And although it"s difficult to see, I"m told the letters immediately below it say "Made in France". Shouldn"t be too difficult to track down the make and manufacturer."
"But you knew about the prints in the garden last night," said Alice. "Why have they suddenly become so-"
"Ah," interrupted Rushton. "But last night we didn"t know about the matching one upstairs."
"Boss, we really shouldn"t be ..." said DI Neasden.
Rushton held up a hand to silence him. "There are three young children in this house," he said. "They need to know this."
"Excuse me," said Alice in a low voice. "Matching one upstairs?"
"On the landing," said Neasden, with a resigned look at his boss. "Right outside your daughter"s room. I"m afraid whoever was in your garden last night was in your house first."
Alice"s fingers rose to her face. It would have been difficult to say which had the least colour.
"Yes, I know, la.s.s," said Rushton. "Very upsetting, but it means we"re getting somewhere."
"I looked last night," said Alice, who didn"t seem to want to believe it. "I didn"t see any sign that anyone had-"
"No, you wouldn"t," replied DI Neasden. "It"s what we call a latent print. Just about invisible to the naked eye and typically left by shoes that are quite clean."
"You see, la.s.s, shoes pick up traces of whatever we walk on," said Rushton. "It"s called Locket"s Law or some such."
"Locard"s Exchange Principle," interrupted Neasden with the first smile Harry had seen on his face. "Every time two surfaces come into contact there"s potential for the exchange of physical materials. We carry away something of what we encounter, everywhere we go."
"Yeah, that"s it." Rushton nodded his head in his DI"s direction. "So, as I was saying, every time we walk on something dust, mud, carpet and so on tiny particles cling to the soles of our shoes and then when our shoes come into contact with a clean, dry surface, such as your floorboards upstairs, Mrs F, they leave a faint print behind. We find them when I say we, I mean my clever lads and la.s.ses in the same way we find fingerprints. We dust with fingerprint powder and then lift the print with adhesive tape."
"Just the one print indoors?" asked Harry. Rushton turned to the inspector for confirmation.
Neasden nodded. "We"re pretty certain there"s nothing else," he said. "I don"t doubt there could have been more last night, but there was a lot of coming and going in the house, even before we got here. Any others were probably lost. Doesn"t matter though. One"s enough."
"You OK, Alice?" asked Harry.
Alice seemed to be getting some of her colour back. She nodded. "Actually, it"s a bit of a relief," she said. "It means Tom wasn"t lying." She was silent for a second. "He"s probably been telling the truth all along," she added.
Harry smiled at her and turned back to Rushton. "Can you trace the boot to its owner?" he asked.
"There"s a good chance." Rushton nodded. "We also, very conveniently, have a tiny gash in the right side of the sole, can you see?" He tapped the side of the photograph with his right index finger. Harry saw a small indentation, only half a centimetre long. "Also, according to our lab, there are wear patterns visible. If we find the boot in question, we can prove the wearer was in your house and garden. Which, given the lack of any sign of a break-in, is why I brought up the subject of changing the locks. Perhaps think about a burglar alarm while you"re at it."
"I"ll ring Gareth," said Alice, getting to her feet. "He can bring some new locks home with him."
"Very wise," agreed Rushton. "But just hold on a sec, la.s.s. I"m afraid that"s not all. You should probably sit down."
Alice looked at the kitchen door. "I really need to check on the kids," she said.
"Evi"s with them," Harry reminded her, wondering if the social worker would offer to go and see if the children were OK. She didn"t. Alice took her seat again.
"Where do you do your dry-cleaning, Mrs Fletcher?" asked Rushton.
"My what?" asked Alice.
"Dry-cleaning. There"s a couple of places down in Goodshaw Bridge, do you use either of those?"
"I suppose I would," agreed Alice, "if I ever had anything to take. But I probably use dry-cleaners once a year."
There was a moment"s silence, while Rushton and Jove exchanged glances.
"I have three children," Alice continued, as though worried they might not believe her. "I paint for a living and my husband is a builder. As a general rule, if something won"t wash, I won"t buy it."
"Sound thinking," said Rushton, nodding his head. "My suits cost a fortune to keep clean, according to the wife. So, have you ever tried these home dry-cleaning kits? You know, when you shove everything in a bag with a load of chemicals and put it in the tumble-dryer?"
"I"ve never heard of such things," said Alice.
"So you won"t mind if Stacey here and her colleagues have a quick look round your cupboards, make sure there"s nothing you"ve forgotten?"
Alice thought about it for a second. "Be my guest," she said. "You won"t find them very tidy."
Rushton turned and nodded to the WPC. She left the room.
"We"re struggling with the dry-cleaning connection," said Harry.
"The floor"s yours, Jove," said Rushton, leaning back in his chair. In the hallway, Harry could hear the sound of the front door opening and closing as someone, he guessed the WPC, left the house.
"The crime-scene investigators found something in your garden last night that puzzled us," said DI Neasden, speaking to Alice. "We thought it was just a tissue of some sort at first but we photographed it, bagged it and took it to the lab, as we do."
The front door opened again. Footsteps were coming towards the kitchen.
"About thirty minutes ago, we got a phone call from them, saying they"ve managed to identify it," he continued. "It"s an essential part of a home dry-cleaning kit. A sort of cotton pad, soaked in stain-removing chemicals, that you put into the tumble-dryer with your clothes. If you do your dry-cleaning at home, that is."
"I"m going to have to talk to the wife about them," said Rushton, who was leaning back quite precariously by this stage.
"Yes, thanks, Boss. Anyway ..."
The kitchen door opened and the WPC was back, with two colleagues, both male. "OK to start in here, sir?" she asked. Rushton nodded, lowering the front legs of his chair to the floor again.
"The utility room"s through there," said Alice, indicating the back door. The two uniformed men left the kitchen, while the WPC knelt down and opened the cupboard under Alice"s sink.
"Where was I?" said DI Neasden. "Right, the dry-cleaning pad. Obviously, we wonder what it"s doing in your garden. It has a strong residue of chemicals clinging to it and it wasn"t particularly wet or muddy when we picked it up, suggesting that, like the footprints, it was left in your garden last night. The lab also say they"ve found traces of the same chemical in your husband"s gym bag."
"The dry-cleaning pad was in the bag," said Harry. Everyone ignored him.
"Any reason why your husband might have a dry-cleaning kit in his gym bag?" asked DI Neasden.
Alice shook her head. "Gareth can"t work the washing machine," she said.
"Now, dry-cleaning fluids have a very distinctive smell," said Rushton, who seemed unable to keep quiet any longer. "You must know, Reverend, all your lovely robes must have to be professionally cleaned."
Harry nodded. "Quite takes your breath away when you take them out of the plastic covers."
"And when we took the sheets off your daughter"s bed, we just got a whiff of something. Well, Jove did, to be honest. Very good nose."
"How has she been today?" asked Neasden. "Have you noticed anything unusual? The GP took a look at her last night, didn"t he?"
"He did," said Alice, who was starting to look frightened again. "I probably should just go and see ..."
"I"ll go," said Harry, getting to his feet. He stepped back from the table and stopped. He didn"t want to leave, he wanted to hear where this was leading.
"The doctor said she seemed fine," continued Alice. "A bit drowsy, but otherwise OK. He wasn"t worried about her, just asked me to bring her in later today."
"Any coughing? Runny nose? Red eyes?" asked Neasden.
Alice nodded. "She has been rubbing her eyes a lot. What"s happened to her?"
"The thing that puzzled us most about your son"s story," said Rushton, "because something was telling me he wasn"t lying, was how this intruder could get a small child into a hold-all without her yelling merry h.e.l.l and waking the entire house up. It"s starting to make a bit more sense now."
"I still don"t see ..." Harry had moved as far as the door.
"The principle component of these dry-cleaning pads is polyglycolether," said DI Neasden.
"What?" said Alice.
"Miss off the fancy first bit," said Rushton. "Ether is what we"re talking about. Been used for donkeys" years as a pretty crude anaesthetic. I"m sorry to say it, but it looks like someone held a pad soaked in ether against Millie"s face. It almost certainly wouldn"t have worked with an adult, probably not even on one of your lads, but given how small she is and the fact that she was sleeping anyway, it was probably just sufficient to keep her drowsy enough to put her in the bag."
Alice gave a tiny cry and set off towards Harry.
"I"m going," he muttered, and pulled open the kitchen door. Four strides took him to the door of the living room. He pulled it open, knowing that Alice was hot on his heels. Evi and the three children were sitting on the floor. Four faces, impossible to say which was the prettiest, turned to him. He was still trying to decide when Alice squeezed past him.
"Um, um," called Millie, her little face lighting up, before squawking in annoyance as her mother scooped her up and pressed her against her chest.
Rushton and DI Neasden came into the room.
"Right then," announced Rushton. "Schoolboy Superhero Tom and his trusty sidekick, Joe the Invincible, I think we need another word with you two."
59.
"PERHAPS THEY"LL PUT A PUT A PLAQUE FOR US HERE AFTER PLAQUE FOR US HERE AFTER we"re dead and gone," said Harry. "Are you cold?" we"re dead and gone," said Harry. "Are you cold?"
"Why?" asked Evi. Are you going to offer me your coat?" Harry carried on staring straight ahead. "I"ll share it," he offered. Evi waited for him to turn towards her, to grin. He didn"t move.
"You look tired," she said, although the truth was he didn"t just look tired. He looked thinner, older. The man she"d met in the hospital that morning hadn"t been the Harry she knew. Someone else had taken his place. Someone else was still there.
"Yeah, well, I spent the first half of the night thinking about you," he said, still keeping his eyes fixed on the building across the street. "Then I got a phone call."
