"Then," said the doctor, "I am quite of opinion that my ideas are correct. These, people probably tracked your cousin to this place, contrived to administer a subtle and deadly poison to him last night, and entered his room after the time at which they knew it would take effect. Have you any clue--even a slight one?" "Only this," answered Allerdyke, and proceeded to narrate the story of the shoe-buckle, adding Fullaway's theory to it. "That's not much, eh?" "You must find that woman and produce her at the inquest," said the doctor. "I take it that Mr. Fullaway's idea is a correct one. Your cousin probably did invite Miss Lennard into his room to show her these jewels--that, of course, would prove that he had them in his possession at some certain hour last night. Now, about that inquest. It is fixed for ten o'clock to-morrow morning. Let me advise you as to your own course of procedure, having an eye on what you have told me. Your object should be to make the proceedings to-morrow merely formal, so that the Coroner can issue his order for interment, and then adjourn for further evidence. It will be sufficient if you give evidence identifying the body, if evidence is given of the autopsy, and an adjournment asked for until a further examination of the reserved organs and viscera can be made. For the present, I should keep back the matter of the supposed robbery until you can find this Miss Lennard. At the adjourned inquest--say in a week or ten days hence--everything pertinent can be brought out. But you will need legal help--I am rather trespassing on legal preserves in telling you so much." "Deeply obliged to you, doctor--and you can add to our obigations by giving us the name of a good man to go to," said Allerdyke. "We'll see him at once and fix things up for to-morrow morning." Dr. Orwin wrote down the name and address of a well-known solicitor, and presently went away. When he had gone, Allerdyke turned to Fullaway. "Now, then," he said, "you and I'll do one or two things. We'll call on this lawyer. Then we'll cable to the Princess. But how shall we get her address!" "There's sure to be a Russian Consul in the town," suggested Fullaway. "Good idea! And I'm going to telephone to this Miss Lennard's address in London," continued Allerdyke. "She evidently set off from here to Edinburgh; but, anyway, the address she gave in that wire to the manager is a London one, and I'm going to try it. Now let's get out and be at work."
