"When I got back with the bag, he had finished. He put on a hat and overcoat and we went out, walked to Victoria Station, and from there took a taxicab to Charing Cross. From there we walked to an all-night Turkish bath establishment, and that gave us an opportunity to change into some rough tweeds that I'd shoved in the bag. In the morning we went to the East End and fixed up rooms with some people I knew of. We had come away without any money, but Grell somehow managed to get in touch with the Princess Petrovska, with whom, apparently, he had some arrangement. She had, it seems, booked through to Paris from Charing Cross, but instead of getting on the boat at Folkestone had returned by the next train and taken quiet lodgings at Kennington. That was to put you on a false track in case of accidents." Foyle smiled a little ruefully. "So that was how it was done," he remarked. "We were determined to get out of the country, but the reward bill with a description of Goldenburg that pictured Grell stopped us trying ordinary methods. It was necessary to raise money, and I, recklessly enough I suppose, went out with the pearls which Mr. Grell had entrusted to me, in the hope of meeting a jeweller, with whom I had a casual acquaintance, at the restaurant, when you fell in with me. The jeweller's letter which you found on me was, by the way, a forgery. "When you seized me I was taken by surprise. When I was allowed to go, after you had told me that the dead man was not Grell, I felt certain that you would have me followed. Your men were very clever, and I could not shake 'em off at first. I was determined to go to any length to protect Grell, so I went into an outfitter's where there was a public telephone, and put a call to a place where I was sure to find Condit. I fixed up with him to wait for the man who was shadowing me, and I led him down to Whitechapel. It was simple enough for Condit to drop on him from behind, and then the two of us knocked him senseless, got him into a cab, and carried him away to Smike Street--to the place which you raided. "Mr. Grell knew nothing about that incident till it was over. He was staying in Grave Street at the time, and the idea occurred to me of holding your man as a hostage. We meanwhile contrived to send a note to Sir Ralph Fairfield. In case of accidents, I was to meet him in Grave Street and lead him round about till I was certain he was not followed." "Then you were the black-bearded man who fired at me!" exclaimed Foyle. "I might have guessed it." "And so you were the navvy!" said Ivan. "I didn't know that, but I at once made up my mind it was dangerous to meddle with Fairfield if he was watched. I gave him the slip, went back to Mr. Grell, and typed out a note to you. You got it?" "Yes. I got it. Where did the paper you used come from?" Ivan's brow contracted into a frown of deep thought. "I forget--no--I got it from Mr. Grell. He tore off a half-sheet from a letter."
