To give any information to the foes of Echford Flagg would be giving odds--and she was working single-handed and deserved odds for herself. She resolved to make her game as peculiar as possible--to keep all of them guessing--to oblige them to take the initiative against her if they should find out the secret of her strange actions. The element of time entered largely into her calculations: every day on which she stood between them and Ward Latisan--every day that he devoted to the drive--was a day to be charged to her side of the ledger; and there are not many days in the driving season when the waters _are_ high and the river is rushing. A keener mind than Crowley's would have detected in Mern's letter all the chief's inability to understand. What Crowley did get from the letter was the conviction that Miss Kennard was not to be molested at that time. Mern made that clear, though he was vague on other points. The chief was wondering whether excess of zeal might be the reason for Miss Kennard's amazing performance. He remembered certain hints which she had dropped as to her financial needs, and she had not seemed averse when he had told her on occasions that he thought of giving her a commission when the right kind of a case came along. To turn a trick for a rich corporation--working alone so that she might claim full credit--undoubtedly had appealed to her as her great opportunity, Mern reflected, and she had set off on her own hook, fearful that he would not alter the arrangements he had made. He was angry; he muttered oaths as he weighed the situation. But he did not put any of his anger into his letter to Crowley. Miss Kennard knew too much about the general inner workings of the agency! In this new case there was specifically a five-thousand-dollar net fee in case Latisan could be eliminated and his crew left to the mercies of Comas bluster and cash. Miss Kennard, if unduly molested, could say two words in the north country and put that contingent fee into limbo. Therefore, Chief Mern was treading softly at first. But from the letter which treated the general situation so gingerly the strong-arm operative extracted one solid and convincing command. He was to watch Miss Kennard. The command seemed entirely natural. Had he not been sent up there to watch--or watch over--no matter which--Miss Elsham? His instructions in regard to Miss Kennard seemed to make her a particularly valuable person in the Vose-Mern plans. He was not to allow anything to interfere with his watching of Miss Kennard, not even for the sake of Miss Elsham. He was to observe every movement, catch every word, if possible, mark every detail of Miss Kennard's operations. Crowley did not show the letter to Miss Elsham, nor did he speak of it. He would mortally offend her by revealing his double-crossing tactics; as a woman she would be more offended by being relegated to the background in favor of the newcomer.
