Gaston Suzor was a shrewd, clever man. But what did this friendship with Gabrielle Tennison denote? As I watched I saw him speaking very earnestly. For some time she sat with her gloved hands idly in her lap listening to his words without comment. Then she shook her head, and put up her hands in protest. Afterwards by her attitude she seemed to be appealing to him, while he remained obdurate and unperturbed. I longed to overhear their conversation, but in the fading light of that brief wintry afternoon it was impossible to approach closer. I could only sit and watch. My eyes were strained to see every gesture of the pair, now that the stout figure of the girl's companion had disappeared towards the Bayswater Road. In that oasis in the desert of aristocratic London one can obtain quite sylvan surroundings. True, the trees and vegetation are covered with a film of grime from the millions of smoking chimneys of the giant metropolis, still Kensington Gardens ever possesses a charm all its own as a clandestine meeting-place for well-born lovers and ill-born loafers, for nursemaids and soldiers, and for persons of both sexes who wish for a little quiet talk in the open air in order so often to clear a hectic atmosphere. Such I judged to be the case between Gaston Suzor and Gabrielle Tennison. At first the girl sat inert with downcast eyes listening to the man. But suddenly she raised her hands in quick protest again, and apparently became resentful--even angry. Then when he spoke some reassuring words she became calmer. As I sat there shrewdly watching, I could not help reflecting upon a still further problem which now presented itself. The very last person in the world whom I should have suspected of being connected with the strange affair at Stretton Street was my affable friend the French banker. I now began to wonder if my first meeting with him in the express train between York and King's Cross just before my amazing adventure had been simply by chance, or had it any connection between that meeting and the trap which had, without a doubt, been so cunningly prepared for me as I passed through Stretton Street to my uncle's house on the following evening. The fact that I had again met the mysterious Suzor at the Gare du Nord, in Paris, just as I was on my way back to London to pursue further inquiries was, in itself, suspicious. I confess that I sat utterly bewildered. One thing was plain, namely, that he had no suspicion that I was keeping such close observation upon Gabrielle. I knew where she lived, and to me he had given his hotel address. At last, after quite twenty minutes of serious conversation, the stout, flat-footed servant returned, and after a few pleasant words with her, Suzor rose, and raising his hat, left them. Instantly it occurred to me that, as I knew the girl's abode, it would be more useful perhaps to watch the movements of my friend the French banker.
