Then he pulled a sheet of paper to him and wrote rapidly:

Dear Mr. Bawdrey—I've got my man, and am off to consult with Mr. Narkom and to have what I've found analysed. I don't know when I shall be back—probably not until the day after to-morrow. You are right. It is murder, and Java is at the bottom of it. Dollops will hand you this. Say nothing—just wait till I get back.

This he slipped, unsigned in his haste, into an envelope, handed it to Dollops, and then fairly jumped into his clothes. Ten minutes later he was out of the house, and—the end of the riddle was in sight.

On the morrow Mrs. Bawdrey made known the rather surprising piece of news that Mr. Rickaby had written her a note to say that he had received a communication of such vital importance that he had been obliged to leave the house that morning before anybody was up, and might not be able to return to it for several days.

"No very great hardship in that, my dear," commented Mrs. Somerby-Miles, "for a more stupid and uninteresting person I never encountered. Fancy! he never even offered to assist the gentlemen to get poor Mr. Bawdrey upstairs last night. How is the poor old dear this morning, darling? Better?"

"Yes—much," said Mrs. Bawdrey in reply. "Doctor Phillipson came to the house before four o'clock, and brought some wonderful new medicine that has simply worked wonders. Of course, he will have to stop in bed and be perfectly quiet for three or four days; but, although the attack was by far the worst he has ever had, the doctor feels quite confident that he will pull him safely through."

Now although, in the light of her apparent affection for her aged husband, she ought, one would have thought, to

be exceedingly happy over this, it was distinctly noticeable that she was nervous and ill at ease, that there was a hunted look in her eyes, and that, as the day wore on, these things seemed to be accentuated. More than that, there seemed added proof of the truth of young Bawdrey's assertion that she and Captain Travers were in league with each other, for that day they were constantly together, constantly getting off into out-of-the-way places, and constantly talking in an undertone of something that seemed to worry them.

Even when dinner was over, and the whole party adjourned to the drawing-room for coffee, and the lady ought, in all conscience, to have given herself wholly up to the entertainment of her guests, it was observable that she devoted most of her time to whispered conferences with Captain Travers. They kept going to the window and looking up at the sky, as if worried and annoyed that the twilight should be so long in fading and the night in coming on. But worse than this, at ten o'clock Captain Travers made an excuse of having letters to write, and left the room, and it was scarcely six minutes later that she followed suit.
