"I happen to have seen this individual," I explained to the police commissary. "I was with Señor Rivero, head of the Spanish detective department, and we saw him at Montauban. But though Señor Rivero followed him, he escaped." "Then he is wanted--eh?" "Yes--for murder." The Dutch police official gave vent to a low grunt. "Very well," he said. "I will have inquiry made. I thank you very much for the information." It seemed to me that he was annoyed because I had dared to dispute his theory that the late Baron had died from natural causes. He was a stolid man, who, having once made up his mind, would not hear any evidence to the contrary. With failing heart I saw that to move him was hopeless, so next day I returned to London, piqued and angry, yet satisfied that I had discovered the true cause of the Baron's lamentable death. Weeks passed. To pursue the inquiry further seemed quite hopeless. The summer went by, but Mrs. Tennison and her daughter still remained in Lyons. The reports were never hopeful. My poor darling was just the same. There recurred to her ever and anon a remembrance of those three colours which haunted her--red, green and gold. The Professor was most kind, Gabrielle's mother wrote me. He did everything in his power, and still persevered after failure upon failure. "I fear poor Gabrielle will never recover," she wrote in one of her letters. "The Professor is always optimistic, but I can read that in his heart he has no hope. The next step will, I dread to think, be hopeless imbecility!" With that letter in my pocket I went to the office in Westminster each day with leaden heart. The joys of life had become blotted out. I cared for nothing, for no one, and my interest in living further had been suddenly swept away. Harry Hambledon, as we sat together at breakfast each day, tried in vain to interest me in various ways. He urged me one evening to go with him and Norah to the Palais de Danse, across Hammersmith Bridge, and I was forced to accept. But instead of dancing I sat at a side table and sipped ice drinks. Dancing had no attraction for me. Very fortunately we were extremely busy at the office. Four big contracts had been entered into by the firm for the lighting and telephones for four new hotels-de-luxe, one at Bude, in Cornwall, one in Knightsbridge, another at Llandudno, in North Wales, and the fourth at Cromer. Hence I was compelled to be ever on the move between Wales, Norfolk, and Cornwall, and perhaps this sudden activity prevented me from brooding too closely over the hopeless condition of the girl with whom I was so deeply in love. In these days electrical engineers have to be pretty active in order to pay their way, and though Francis and Goldsmith was an old-established firm, they were nothing if not up-to-date in their methods. One morning as I sat in a corner of the London-Exeter express on my way down to Bude, I read in my paper the following:
