“Mr. Isaacs represented himself as a dealer in Covent Garden who was leasing the office for a lady friend, and who desired, for domestic reasons, to cover his tracks. As ready money in large amounts changes hands in the market, Mr. Isaacs paid ready money to the agent. Beyond doubt the real source of the ready money was Kazmah’s.”

“But his address?”

“A hotel in Covent Garden.”

“Where he lives?”

“Where he is known to the booking-clerk, a girl who allowed him to have letters addressed there. A man of smoke, sir, acting on behalf of someone in the background.”

“Ah! and these Bond Street premises have been occupied by Kazmah for the past eight years?”

“So I am told. I have yet to see representatives of the landlord. I may add that Sir Lucien Pyne had lived in Albemarle Street for about the same time.”

“Not a grain, sir!”
