While it was true he did not as yet know what had become of the Montalais jewels, he had gathered together an accumulation of evidence which, however circumstantial and hypothetical, established acceptably to his intelligence a number of interesting inferences, to wit:

That Dupont had not left the neighbourhood of the Château de Montalais, after haunting it for upwards of a month, without definite knowledge that he would gain nothing by staying on, or without an equally definite objective, some motive more inspiring than such simple sensuousness as he might find in assassinating inoffensive folk indiscriminately.

That his attempt upon the life of Liane Delorme within twenty-four hours of the murder of de Lorgnes indicated conviction on his part that the two were coupled in some enterprise inimical to his personal interests.

That in spite of his mask of a stupid pig Dumont was proving himself mentally as well as physically an adversary worthy of all respect, and was--what was worse--still to be reckoned with.

That, as Lanyard had suspected all along, the Monk party had been visited upon the Château de Montalais through no vagary of chance whatever but as part of a deliberate design whose ulterior motive had transpired only with the disappearance of the jewels--to Dupont's vast but understandable vexation of spirit.

That the several members of the Monk party had been working in entire accord, as a close corporation; in which case the person whom the Comte de Lorgnes had expected to meet in Lyons must have been Monk Phinuit or Jules.

Consequently that at least one of the three last named had been the actual perpetrator of the robbery; and by the same token, that Liane had lied in asserting that Monk and retinue had sailed for America nearly a week prior to its commission.

That Liane herself had not so suddenly decided to leave France, where she was after a fashion somebody, and journey to America, where she would be nobody, except in stress of mortal fear lest the fate that had befallen de Lorgnes befall her in turn--as would surely have been the case last night but for Lanyard.

That she must therefore have had a tolerably accurate knowledge either of Dupont's identity or of the opposition interests which that one so ably represented; and thus was better informed than poor de Lorgnes, to whom Dupont had been unknown; which argued that Liane's rôle in the intrigue was that of a principal, whereas de Lorgnes had figured only as a subordinate.

That even if the woman did mean well toward Lanyard she was bound by stronger ties to others, whom she must consider first, and who were hardly likely to prove so well disposed; that her protestations of friendship and gratitude must be valued accordingly.
