Carnes stepped a little closer to the doctor.
"Another reason why I didn"t want patrolmen tramping around," he said in an undertone, "is this. If Winston gave the alarm quickly enough, the thief is probably still in the building."
"He"s a good many miles away by now," replied Dr. Bird with a shrug of his shoulders.
Carnes" eyes opened widely. "Why?--how?--who?" he stammered. "Have you any idea of who did it, or how it was done?"
"Possibly I have an idea," replied Dr. Bird with a cryptic smile. "My advice to you, Carnes, is to keep away from the local authorities as much as possible. I want to be present when Winston and Trier are questioned and I may possibly wish to ask a few questions myself. Use your authority that far, but no farther. Don"t volunteer any information and especially don"t let my name get out. We"ll drop the counterfeiting case we were summoned here on for the present and look into this a little on our own hook. I will want your aid, so don"t get tied up with the police."
"At that, we don"t want the police crossing our trail at every turn,"
protested Carnes.
"They won"t," promised the doctor. "They will never get any evidence on this case, if I am right, and neither will we--for the present. Our stunt is to lie low and wait for the next attempt of this nature and thus acc.u.mulate some evidence and some idea of where to look."
"Will there be another attempt?" asked Carnes.
"Surely. You don"t expect a man who got away with a crime like this to quit operations just because a few flatfeet run around and make a hullabaloo about it, do you? I may be wrong in my a.s.sumption, but if I am right, the most important thing is to keep all reference to my name or position out of the press reports."
The cashier hastened up to them.
"Detective-Captain Sturtevant will be here in a few minutes with a photographer and some other men," he said. "Is there anything that we can do in the meantime, Mr. Carnes?"
"I would suggest that Mr. Trier and his guard and Mr. Winston go into your office," replied Carnes. "My a.s.sistant and I would like to be present during the questioning, if there are no objections."
"I didn"t know that you had an a.s.sistant with you," answered the cashier.
Carnes indicated Dr. Bird.
"This gentleman is Mr. Berger, my a.s.sistant," he said. "Do you understand?"
"Certainly. I am sure there will be no objection to your presence, Mr.
Carnes," replied the cashier as he led the way to his office.
A few minutes later Detective-Captain Sturtevant of the Chicago police was announced. He acknowledged the introductions gruffly and got down to business at once.
"What were the circ.u.mstances of the robbery?" he asked.
Winston told his story, Trier and the guard confirming it.
"Pretty thin!" snorted the detective when they had finished. He whirled suddenly on Winston.
"Where did you hide the loot?" he thundered.
"Why--uh--er--what do you mean?" gulped the teller.
"Just what I said," replied the detective. "Where did you hide the loot?"
"I didn"t hide it anywhere," said the teller. "It was stolen."
"You had better think up a better one," sneered Sturtevant. "If you think that you can make me believe that that money was stolen from you in broad daylight with two men in plain sight of you who didn"t see it, you might just as well get over it. I know that you have some hiding place where you have slipped the stuff and the quicker you come clean and spill it, the better it will be for you. Where did you hide it?"
"I didn"t hide it!" cried the teller, his voice trembling. "Mr. Trier can tell you that I didn"t touch it from the time I laid it down until I turned back."
"That"s right," replied the paymaster. "He turned his back on me for a moment, and when he turned back, it was gone."
"So you"re in on it too, are you?" said Sturtevant.
"What do you mean?" demanded the paymaster hotly.
"Oh nothing, nothing at all," replied the detective. "Of course Winston didn"t touch it and it disappeared and you never saw it go, although you were within three feet of it all the time. Did _you_ see anything?" he demanded of the guard.
"Nothing that I am sure of," answered the guard. "I thought that a shadow pa.s.sed in front of me for an instant, but when I looked again, it was gone."
Dr. Bird sat forward suddenly. "What did this shadow look like?" he asked.
"It wasn"t exactly a shadow," said the guard. "It was as if a person had pa.s.sed suddenly before me so quickly that I couldn"t see him. I seemed to feel that there was someone there, but I didn"t rightly _see_ anything."
"Did you notice anything of the sort?" demanded the doctor of Trier.
"I don"t know," replied Trier thoughtfully. "Now that Williams has mentioned it, I did seem to feel a breath of air or a motion as though something had pa.s.sed in front of me. I didn"t think of it at the time."
"Was this shadow opaque enough to even momentarily obscure your vision?"
went on the doctor.
"Not that I am conscious of. It was just a breath of air such as a person might cause by pa.s.sing very rapidly."
"What made you ask Trier if he had the money when you turned around?"
asked the doctor of Winston.
"Say-y-y," broke in the detective. "Who the devil are you, and what do you mean by breaking into my examination and stopping it?"
Carnes tossed a leather wallet on the table.
"There are my credentials," he said in his quiet voice. "I am chief of one section of the United States Secret Service as you will see, and this is Mr. Berger, my a.s.sistant. We were in the bank, engaged on a counterfeiting case, when the robbery took place. We have had a good deal of experience along these lines and we are merely anxious to aid you."
Sturtevant examined Carnes" credentials carefully and returned them.
"This is a Chicago robbery," he said, "and we have had a little experience in robberies and in apprehending robbers ourselves. I think that we can get along without your help."
"You have had more experience with robberies than with apprehending robbers if the papers tell the truth," said Dr. Bird with a chuckle.
