But Ashton-Kirk with an impatient gesture stopped him.

"Indications are not proof," said he, as he went into the hall. "Don't forget that we ourselves have also made tracks round about the window below, our shoes are also more or less caked with earth, and we have both spoken to Okiu."

"Of course that's so," said Fuller, "but nevertheless the facts are peculiar." He followed the other along the hall and into a room at the front of the house. "But, for that matter, everything having to do with this case is peculiar. I never saw a trail so snarled and crossed and recrossed. First you get the idea of a Japanese. Then Warwick is plunged into the thing so deep that I fail to see how he's ever going to extricate himself. Thirdly, we have enough proof as to Drevenoff's complicity to put him behind the bars; and now the probabilities are that the girl is also concerned."

Ashton-Kirk moved slowly about the room; it was one evidently used by Dr. Morse as a sort of lounging place, for there were sofas and big chairs and many books. At one side near the front window was a narrow antique desk of polished wood; it was open, and its contents had been tumbled about by the police. Ashton-Kirk sat down before it, annoyed and frowning.

"After an Osborne and a deputy coroner have been over the ground, one could drive a herd of mules over it without causing any appreciable difference in its aspect," said he. "They are as heavy handed as draymen."

And while he proceeded with a careful inspection of the contents of the desks, Fuller continued in a complaining tone:

"I'd like to know what we are to make of the whole business. Is it a sort of general conspiracy against Dr. Morse? Are Warwick, Miss Corbin and Drevenoff in league with the Jap for some particular purpose?—are there factions in the matter—each working for its own advantage?—or is every individual laboring for him or herself, and against all the others?"

"Mostly correspondence of a private nature," said Ashton-Kirk, as he ran through the papers. "Contracts with publishers, notes as to lectures, and negotiations for the delivery of the same."

There were some bits of jewelry of no particular value, a few small books of accounts and various odds and ends.

After some further search he lifted the writing bed of the desk, which was also the lid, and was about to close it; something seemed to attract his attention and he paused.
