"You'll find him a match for you," said the Doctor, grimly, as he accompanied his guests to the door.

"Then I'll see Marson."

"Humph! two stools, you'll fall to the ground."

"I'll take my chance of that," said Fanks, cheerfully, as he stepped out into the darkness with Roger. "Good night, Japix. I'll be able to give you the key to the Jarlchester Mystery next week."

Extracts From a Detectives Note-Book

". . . Just returned from an evening with Japix . . . We (R., J., and myself) had a long conversation about the case . . . This conversation has left me in a state of great perplexity . . . I told Japix I would give him the key to the mystery next week, but I spoke more boldly than I have reason to . . . It is true I am narrowing down the circle . . . I suspect two people, with a possible third . . . Marson, Judith Varlins, and Judas . . . It's a very humiliating fact to confess this indecision even to myself . . . But, detectives are not infallible save in novels . . . I am perplexed . . . I have suspected Axton wrongfully . . . I have suspected Spolger wrongfully, and now . . . Let me make a note of the motives of each of the three people I suspect now . . .

". . . Marson! He is on the verge of bankruptcy . . . only one person can save him, viz. Jackson Spolger . . . He, however, declines to help him unless he marries Florry Marson . . . She won't marry Spolger because of her love for Melstane . . . A strong motive here for Marson to get rid of Melstane . . .

". . . Miss Varlins . . . Her motive for getting rid of Melstane, I think, is a mixture of love and jealousy . . . Both strong motives, with a woman . . .

". . . Judas! He loves Miss Marson also, and with his loose morality would have no hesitation in putting Melstane out of the way. He wants Florry Marson, he wants her money . . . Melstane stands in the way of his obtaining both . . . in such a case Judas is just the man—from my reading of his character—to commit a crime . . . Again, his employment as a chemist offers him peculiar advantages for obtaining morphia . . . It would be difficult for either Marson or Miss Varlins to obtain morphia in a large quantity, but Judas could easily get it in the ordinary course of his business . . . I am going to see Judas, and from a second conversation may perhaps learn something useful . . . He is crafty . . . still he may betray himself . . . at all events, it is worth while trying.

"Mem.—To see Judas to-morrow night."
