Here again the difficulties, though not quite so overwhelming, were sufficiently great as almost to negative the suggestion. Of one thing French felt convinced; that neither Roper nor any other man in Roper’s position could have carried out such an enterprise singlehanded. One or more confederates would have been absolutely necessary. To mention a single point only, no one person would have had the physical strength to perform such a task. No one person, furthermore, could have taken the requisite precautions against surprise or discovery, nor could one person have carried out the needful transport arrangements between the cemetery and Starvel. The whole subject, as French thought out its details, was indescribably gruesome and revolting. But so interested was he in its purely intellectual side—as a problem for which a solution must be found—that he overlooked the horror of the actual operations. For him the matter was one of pure reason. He did not consider the human emotions involved except in so far as these might influence the conduct of the actors in the terrible drama. Assuming then that the remains had not been procured from a cemetery, there remained but one alternative—murder! Some unknown person must have been inveigled into that sinister house and there done to death, so as to provide the needful third body! If Roper were guilty of the Starvel crime as French now understood it, it looked as if he must have been guilty of a third murder, hitherto unsuspected. Here was food for thought and opportunity for inquiry. Who had disappeared about the time of the tragedy? Was any one missing in the neighbourhood? Had any one let it be known that he was leaving the district or going abroad about that date? Instead of being at the end of his researches, French was rather appalled by the magnitude of the investigation which was opening out in front of him. To obtain the necessary information might require the prolonged activities of a large staff. He was anxious not to give away the lines on which he was working. He decided therefore not to make his inquiries from Sergeant Kent at the local station, but to go to Leeds and have an interview with the Chief Constable. Accordingly, unconsciously following the example of Oxley and Tarkington several weeks earlier, he took the 3.30 train that afternoon and two hours later was seated in Chief Constable Valentine’s room at police headquarters. The old gentleman received him very courteously, and for once French met some one who seemed likely to outdo him in suavity and charm of manner.
