“But you are harbouring me.”

“At the orders of Il Passero.”

“You surely can tell me what you know of Mademoiselle,” Hugh persisted after a brief pause. “We are mutually her friends. The attempt to kill her is outrageous, and I, for one, intend to do all I can to trace and punish the culprit.”

“They say that you shot her.”

“Well—you know that I did not,” Henfrey said. “Have you yourself ever met Mademoiselle?”

“I have seen her. She was living for a time at Santa Margherita last year. I had a friend of hers living here with me and I went to her with a message. She is a very charming lady.”

“And a friend of Il Passero?”

The Italian shrugged his shoulders with a gesture of ignorance.

Hugh Henfrey had certainly learned much that was curious. He had never before heard of the interesting cosmopolitan thief known as The Sparrow, but it seemed evident that the person in question had suddenly become interested in him for some obscure and quite unaccountable reason.

As day followed day in that humble place of concealment, Beppo told him many things concerning the famous criminal Il Passero, describing his exploits in terms of admiration. Hugh learnt that it was The Sparrow who had planned the great jewel robbery at Binet’s, in the Rue de la Paix, when some famous diamonds belonging to the Shah of Persia, which had been sent to Paris to be reset, were stolen. It was The Sparrow, too, who had planned the burglary at the art gallery of Evans and Davies in Bond Street and stolen Raphael’s famous Madonna.
