"Has he? Well, I only hope Henshaw has not been playing the fool, or worse, and caused all this fuss for nothing."
The party moved on to the great hall where the dancing had taken place, and so to the pa.s.sage connecting the main building with the ancient tower.
"Now this is the part which will no doubt interest you most, Mr. Piercy,"
Morriston said; "this fourteenth century tower, which is to-day in a really wonderful state of preservation."
"Ah, yes," the archaeologist murmured; "they could build in those days."
They examined the two lower rooms on the ground and first floors, remarked on the thickness of the walls, shown by the depth of the window embrasures, which in older days had been put to sterner purposes; they admired the solid strength of the ties and hammer-beams in the roofs, and scrutinized the few articles of ancient furniture and tapestry the rooms contained, and the ma.s.sive oaken iron-bound door which admitted to the garden.
"Now we will go up to the top room," Morriston proposed. "It is used only for lumber, but there is quite a good view from it."
He preceded the rest of the party up the winding stairs to the topmost door.
"Hullo!" he exclaimed, pushing at it, "the door is locked. And the key appears to have been taken away," he added, bending down and feeling about in the imperfect light.
The whole party was consequently held up on the narrow stairs. "I"ll go and ask what has become of the key," Morriston said, making his way past them.
In a minute he returned, presently followed by the butler.
"How is it that this top door is locked, Stent?" he asked. "And where is the key?"
"I don"t know, sir. Alfred mentioned this morning that the door was locked and the key taken away; we thought you must have locked it, sir."
"I? No, I"ve not been up here since the morning of the ball, when I had those old things brought up from the lower room to be out of the way."
"Did you lock the door then, sir?"
"No. Why should I? I am certain I did not. Perhaps one of the men did.
Just go and inquire. And have the key looked for."
"Very good, sir."
"This is rather provoking," Morriston said, as they waited. "I particularly wanted to show you the view, which should be lovely on a clear day like this. If we have to wait much longer the light will be going. Besides, it is quite a quaint old room with a curious recess formed by the bartizan you may have noticed from outside."
Presently the butler returned accompanied by a footman with several keys.
"We can"t find the right key, sir," he announced. "No one seems to have seen it. Alfred has brought a few like it, thinking one might possibly fit."
None of them, however, would go into the lock, not even the smallest of them.
"I can"t make it out, sir," said the man, kneeling to get more effectively to work. But no key would enter. The footman at last took a box of matches from his pocket, struck a light and, holding it to the key-hole, peered in.
"Why, the key is in the lock, on the other side, sir," he said in astonishment.
"Then the door can"t be locked," Morriston said, pushing it.
The footman rose and pushed too, but the door showed no sign of yielding; it was fastened sure enough.
"This is strange," Morriston said. "Hi! Is any one in there?" he shouted; but no response came.
"Are you sure the key is in the door on the inside?" he asked.
"Certain, sir. Will you look for yourself, sir?" the man replied, striking another match and holding it so that his master could convince himself.
"No doubt about that," Morriston declared, as he rose from his scrutiny.
"It is the most extraordinary thing I have ever known. Can you account for it, Stent?"
The butler shook his head. "No, sir. Unless someone is in there now."
Morriston again shouted, but no answer came.
"I presume there is no way out of the room but this door," Piercy asked.
"None," Morriston answered; "except the window, and that is, I should say, quite eighty feet from the ground; eh, Mr. Gifford?"
"A sheer drop of quite that distance," he answered.
"A prohibitive mode of exit," Piercy observed with a smile.
"Yes," Morriston said. "I can"t understand it at all. Besides, who would be likely to want to play tricks here? We have had no sign of burglars, and in any case they would hardly have been able to bring a ladder long enough to reach up to that window. Well, we must have the mystery cleared up. I think, Stent, you had better send one of the men on a bicycle into Branchester to fetch a locksmith and have the door opened somehow. Have it explained to him that it may be a tough job. In the meantime we may as well go and view the tower from the outside, as we can"t get in."
Accordingly the whole party went down into the hall and so out to the garden, where they strolled round the house, Piercy meanwhile taking notes of its architectural features. As they came to the tower the rays of a late winter sun were striking it almost horizontally, lighting it up in a picturesque glow. Piercy, with his archaeological knowledge, was able to tell the owner and Gifford a good deal about the ancient structure of which they had previously been ignorant.
"The sunset would have been worth seeing from that top window,"
Morriston said, evidently perplexed and annoyed over the mystery of the locked door. "I can"t make out what has happened."
"The person who locked the door a.s.suredly did not make his exit by the window," Kelson remarked with a laugh, as he looked up at the sheer surface of the upper wall; "unless he was bent on suicide, in which case we should have found what was left of him at the foot of the tower."
As they went on round the house, Miss Morriston was seen coming up the drive. Her brother hurried forward to meet her.
"I say, Edith," he exclaimed, "we are in a great fix. Can you explain how the door of the top room in the tower comes to be locked with the key inside?"
Miss Morriston looked surprised. "What, d.i.c.k?"
"We can"t get in," Morriston explained. "We found the door locked and the key missing, and then when Alfred tried another key, he found the right one was in the lock but inside the room."
Miss Morriston thought a moment. "My dear d.i.c.k, the door can"t be locked."
"It is, I tell you," he returned; "most certainly locked. We have tried it and found it quite fast."
"Then there must be someone in the room," his sister said.
"That," Morriston replied, "seems the only possible explanation. But I shouted several times and got no answer."
"Someone playing you a trick," and the girl laughed.
"But who? who?" he returned.
