There was a movement of men turning and then a sudden stillness, as of their stiffening, for over in the corner on the wooden floor there was really a round spot of pale light. It was the only spot of light in the room. The cigar had gone out.
“It points the way,” came the voice of the oracle. “The spirits are pointing the way to penitence, and urging the thief to restitution. I can see nothing more.” His voice trailed off into a silence that lasted solidly for many minutes, like the long silence below when the theft had been committed. Then it was broken by the ring of metal on the floor, and the sound of something spinning and falling like a tossed halfpenny.
“Light the lamp!” cried Fisher in a loud and even jovial voice, leaping to his feet with far less languor than usual. “I must be going now, but I should like to see it before I go. Why, I came on purpose to see it.”
The lamp was lit, and he did see it, for St. Paul’s Penny was lying on the floor at his feet.
“Oh, as for that,” explained Fisher, when he was entertaining March and Twyford at lunch about a month later, “I merely wanted to play with the magician at his own game.”
“I thought you meant to catch him in his own trap,” said Twyford. “I can’t make head or tail of anything yet, but to my mind he was always the suspect. I don’t think he was necessarily a thief in the vulgar sense. The police always seem to think that silver is stolen for the sake of silver, but a thing like that might well be stolen out of some religious mania. A runaway monk turned mystic might well want it for some mystical purpose.”
“No,” replied Fisher, “the runaway monk is not a thief. At any rate he is not the thief. And he’s not altogether a liar, either. He said one true thing at least that night.”
“And what was that?” inquired March.
“He said it was all magnetism. As a matter of fact, it was done by means of a magnet.” Then, seeing they still looked puzzled, he added, “It was that toy magnet belonging to your nephew, Mr. Twyford.”
“But I don’t understand,” objected March. “If it was done with the schoolboy’s magnet, I suppose it was done by the schoolboy.”
