To me it now seemed plain that I had been marked down as a pawn in the game prior to that day when we travelled together from York to London. I had not altogether recovered from the effect of what had been administered to me. Often I felt a curious sensation of dizziness and of overwhelming depression, which I knew was the after effects of that loss of all sense of my surroundings when I had been taken to the hospital in St. Malo. I had been found at the roadside in France, just as Gabrielle had been found on the highway near Petersfield. When I reflected my blood boiled. The affable and highly cultured Frenchman presented a further enigma. He was crossing back to Paris next day. What if I, too, went back to Paris and watched his further movements? As I sat chatting and laughing with him, I decided upon this course. When, shortly afterwards, I left, I went straight across Hammersmith Bridge and found that Harry Hambledon had just returned from his office. We sat together at table, whereupon I told him one or two facts I had discovered, and urged him to cross to Paris with me next day. "You see, you can watch--for you will be a perfect stranger to Suzor. I will bear the expense. I've still got a little money in the bank. We can see Suzor off from Charing Cross, then take a taxi to Croydon, fly over, and be in Paris hours before he arrives at the Gare du Nord. There you will wait for his arrival, follow him and see his destination." Hambledon, who was already much interested in my strange adventures, quickly saw the point. "I've got one or two rather urgent things on to-morrow," he replied. "But if you really wish me to go with you I can telephone to my friend Hardy and ask him to look after them for me. We shan't be away very long, I suppose?" "A week at the most," I said. "I want to establish the true identity of this banker friend of mine. I have a distinct suspicion of him." "And so have I," Hambledon said. "Depend upon it, some big conspiracy has been afoot, and they are now endeavouring to cover up all traces of their villainy. I was discussing it with Norah when we were walking in Richmond Park last night." "I quite agree," I replied. "Then we'll fly across to Paris at lunch-time to-morrow, and keep watch upon this man who meets Miss Tennison in secret and then uses a thieves' sanctuary in order to escape." "That story of the absconding customer of the bank is a fiction, I believe," Harry exclaimed. "I'm certain it is," I said. "Then why should he have told it to you if he did not suspect that you had been watching?" my friend queried. I had not considered that point. It was certainly strange, to say the least, that he should thus have endeavoured to mislead me.
