doubt
of it. I expect Sir Lucien carried the keys on his person. You will
remember, sir, that his pockets had been emptied?"

"H'm," mused the Assistant Commissioner. "This Cubanis Cigarette
Company, Chief Inspector?"

"Dummy goods!" rapped Kerry. "A blind. Just a back entrance to Kazmah's
office. Premises were leased on behalf of an agent. This agent--a
reputable man of business--paid the rent quarterly. I've seen him."

"And who was his client?" asked the Assistant Commissioner, displaying a
faint trace of interest.

"A certain Mr. Isaacs!"

"Who can be traced?"

"Who can't be traced!"

"His checks?"

Chief Inspector Kerry smiled, so that his large white teeth gleamed
savagely.

"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

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

"Now we come to the drug traffic, Chief Inspector. You have found no
trace of drugs on the premises?"

"Not a grain, sir!"

"In the office of the cigarette firm?"

"No."

"By the way, was there no staff attached to the latter concern?"

Kerry chewed viciously.

"No business of any kind seems to have been done there," he replied.
"An office-boy employed by the solicitor on the same floor as Kazmah
has seen a man and also a woman, go up to the third floor on several
occasions, and he seems to think they went to the Cubanis office. But
he's not sure, and he can give no useful description of the parties,
anyway. Nobody in the building has ever seen the door open before this
morning."

The Assistant Commissioner sighed yet more wearily.

"Apart from the suspicions of Miss Margaret Halley, you have no sound
basis f
