He had been disappointed in those who were to have helped him in his task; and it was to his own patience and resources that he was for the most part indebted for such progress as he had made. Drubarde, the ex-police-officer, had been able to do no more than to supply the formal record of the evidence before the _Juge d'Instruction_. He could throw no light upon the previous history of the supposed murderer: he could offer no clue to his subsequent fate. Sigismond Trottier, from whose keen wit Heathcote had hoped for such valuable aid, had broken down altogether. He had failed to furnish any further reminiscences of his old acquaintance Georges. "I want to know what the man was like," said Heathcote, at their last interview. "If you could put me into communication with any artist friend of yours who knew Georges well, and can remember him well enough to give me his likeness from memory--were it the slightest sketch--I would pay your friend liberally for his work, and be very grateful to you for bringing the matter about." "I know no such man," answered Trottier curtly. "That is very strange. Surely there must be some such person among those who can remember Georges. You say that his only friends were of the literary and artistic world." "_Nom d'un nom_", exclaimed Trottier impatiently, "I suppose I had better be frank with you. Yes, it is quite possible there may be some one who knew Georges, and who could give you such a sketch as you want. But I will not help you to find that person. I liked Georges--liked him well, mark you. I have profited by his generosity, have gone to him for help when I was in very low water. I am not going to turn and sting my benefactor. Granted that he was an assassin. I can find excuses even for that crime, for I know how he loved Marie Prévol. I am not going to help you to hunt him down. If he is alive and has repented his sin, let him alone, to be dealt with by his Creator and his Judge. What are we that we should pretend to condemn or to punish him?" "I have sworn to myself to find the last link in the chain." "Why should you want to hunt this man down?" "That is my secret. I have a motive, and a very powerful one. It may be that I have no intention to betray the wretch to justice; that when the tangled skein shall be unravelled, and the mystery of that man's life made clear, that in the hour of success I may be merciful, may hold my hand, and keep the murderer's secret from the outside world. But I want to know that secret, I want to be able to stand face to face with that man and to say, 'You are the murderer of Marie Prévol and her lover; you are the murderer of the helpless girl who went alone to England, having in her possession certain papers which threw too strong a light upon your guilty past. You, who have held your head erect before the world, and have passed for a man of honour and probity, you are the remorseless villain whose life stands twice forfeited to the law.'"
