"Hang it all," replied Hunter; "you can't call it a mystery. Why, we all saw him take it ourselves."

"Yes," replied the other, "but we didn't all see him lose it ourselves. And the mystery is, where has he lost it so that we can't find it?"

"It must be somewhere," said Hunter. "Have you searched the fountain and all round that rotten old god there?"

"I haven't dissected the little fishes," said Hardcastle, lifting his eyeglass and surveying the other. "Are you thinking of the ring of Polycrates?"

Apparently the survey, through the eye-glass, of the round face before him, convinced him that it covered no such meditation on Greek legend.

"It's not on him, I admit," repeated Hunter, suddenly, "unless he's swallowed it."

"Are we to dissect the Prophet, too?" asked the other smiling. "But here comes our host."

"This is a most distressing matter," said Lord Mounteagle, twisting his white moustache with a nervous and even tremulous hand. "Horrible thing to have a theft in one's house, let alone connecting it with a man like the Master. But, I confess, I can't quite make head or tail of the way in which he is talking about it. I wish you'd come inside and see what you think."

They went in together, Hunter falling behind and dropping into conversation with Father Brown, who was kicking his heels round the cloister.

"You must be very strong," said the priest pleasantly. "You held him with one hand; and he seemed pretty vigorous, even when we had eight hands to hold him, like one of those Indian gods."
