Whenever he called the Baron and he held close consultation, sometimes for hours. We travelled to Eastbourne, Bournemouth, Birmingham, Edinburgh, Glasgow, and other cities, yet ever and anon the shabby old Dutchman seemed to turn up at odd times and places, as though springing from nowhere.

When absent from London, the Baron frequently sent telegraphic messages in cipher to a registered address in London. Were these, I wondered, intended for Hartmann or for the mysterious Van Nierop?

The old fellow seemed to haunt us everywhere, dogging our footsteps continually, and appearing in all sorts of out-of-the-way places with his long, greasy overcoat, shabby hat, and shuffling gait, by which many mistook him for a Hebrew.

And the more closely I watched my aristocratic master, the more convinced I became that Van Nierop and he were acting in collusion. But of what was in progress I could obtain no inkling.

Frequently we moved quickly from one place to another, as though my master feared pursuit, then we went suddenly to Aix, Vichy, and Carlsbad, and remained away for some weeks. Early in the autumn we were back again at a suite of well-furnished chambers in Clarges Street, off Piccadilly.

"I expect, Dickson, that we shall be in London some months," the Baron had said to me on the second morning after we had installed ourselves with our luggage. The place belonged to a wealthy young peer of racing proclivities, and was replete with every comfort. All had been left just as it was, even to an open box of cigars. His lordship had gone on a trip round the world.

On the third day—a very wet and dismal one, I recollect—the old Dutchman arrived. The Baron was out, therefore he waited—waited in patience for six long hours for his return. When my master re-entered, the pair sat together for half an hour. Then suddenly the Baron shouted to me, "Dickson! Pack my suit-case and biggest kit-bag at once. Put in both dress-coat and dinner-jacket. And I shan't want you. You'll stay here and mind the place."

"Yes, sir," I replied, and began briskly to execute his orders.

When the shabby old fellow had gone, the Baron called me into the sitting-room and gave me two cipher telegrams, one written on the yellow form used for foreign messages. The first, which he had numbered "1" in blue pencil, was addressed "Zaza, Berlin," and the second was to "Tejada, Post Office, Manchester."

"These, Dickson, I shall leave with you, for I may want them despatched. Send them the instant you receive word from me. I will tell you which to send. It's half-past eight. I leave Charing Cross at nine, but cannot give you any fixed address. Here's money to get along with. Wait here until my return."
