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.
