"No, sir," the commissionaire answered. "But when I made my round after daylight I had a special look at these stones, and I saw at once that someone had been meddling with them. Then I called you, sir, and told you. I was backwards and forwards all night, and I never saw a soul or heard a sound."
"Come up and have some breakfast with me," said Mortimer, and he took me into his own chambers.—"Now, what DO you think of this, Jackson?" he asked.
"It is the most objectless, futile, idiotic business that ever I heard of. It can only be the work of a monomaniac."
"Can you put forward any theory?"
A curious idea came into my head. "This object is a Jewish relic of great antiquity and sanctity," said I. "How about the anti-Semitic movement? Could one conceive that a fanatic of that way of thinking might desecrate——"
"No, no, no!" cried Mortimer. "That will never do! Such a man might push his lunacy to the length of destroying a Jewish relic, but why on earth should he nibble round every stone so carefully that he can only do four stones in a night? We must have a better solution than that, and we must find it for ourselves, for I do not think that our inspector is likely to help us. First of all, what do you think of Simpson, the porter?"
"Have you any reason to suspect him?"
"Only that he is the one person on the premises."
"But why should he indulge in such wanton destruction? Nothing has been taken away. He has no motive."
"Mania?"
