"Yours faithfully,
"W. BENTHAM."
The second document was also in the shape of a letter from a firm of private detective agents and was dated only a day earlier than the lawyer's letter. It ran as follows:
"MY DEAR SIR,—
"In reply to your inquiry, our charges for watching a single person in London only are three guineas a day, including all expenses. For that sum we can guarantee that the person with whose movements you desire to keep in touch will be closely shadowed from roof to roof, so long as the person remains within seven miles of Charing Cross. A daily report will be made to you, and should legal proceedings ensue from any information procured by us, you may rely upon any witness whom we might place in the box.
"Trusting to hear from you,
"We are, yours sincerely,
"McKENNA & FOULDS."
The third document which Wrayson had preserved was the Cunard sailing list for the current month, the plan of a steamer which sailed within a week of the murder, and a few lines from the steamship office respecting accommodation.
"These, at any rate, will give you something to do," Wrayson remarked. "You can go to the lawyer and find out who his client was who desired to see your brother. There is a chance there! You can go to McKenna & Foulds and find out who it was whom he wanted shadowed, and you can go to the Cunard office and see whether he really intended sailing for America."
