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.

Crowley found his espionage an easy job at first. All he had to report to Mern for three or four days was that “Patsy Jones” did her work in the hotel and remained in her room till after dark—and then went out and strolled aimlessly. She would not talk with Crowley when he grasped at opportunities to speak to her on her walks. She reminded him that fellow operatives must be careful; furthermore, scandal might oblige her to abandon her job; he would be responsible if he insisted on dogging her about the village.

However, Crowley was able, a few days later, to slip her a letter from Mern; the chief had inclosed it in a missive containing further instructions to the operative to make sure of every move of Lida. The inclosed letter was addressed to “Patsy Jones.”

Lida read it when she was back in her room. She noted with satisfaction that Chief Mern was still guessing and that his detective mind was unable to solve the mystery except on the ground that she was so loyal to the agency and so ambitious for herself that she had tackled the job as a speculation. He chided her because she had not reported her intention. He asked for a full statement.

She hid the letter carefully in her bureau. Having put it away for further reference in case she did make up her mind to answer the questions when forced to do so, she delayed replying. She did not want to lie needlessly to Mern—she was willing to let him do imagining, too, seeing how well it was working, to all appearances, in the cases of Elsham and Crowley.

She had her own reasons for keeping withindoors in the daytime. The matter of Rickety Dick was worrying her. He had seen her as a girl of sixteen, worn with her vigils beside a sick mother; the light through the area windows had been dim, and he had stumbled against chairs in the room as if his vision were poor.

However, she discovered at the outset of her stay in Adonia that she had become the object of old Dick’s intent regard whenever he found opportunity. He often trudged past the tavern on his errands; he dragged slow steps and squinted and peered. Once she caught him peeping at her through the open door of the dining room. She had feared some such closer inspection and had drawn back her hair and twisted its waviness into an unsightly pug; the moment she saw him she slipped into her mouth a piece of spruce gum which an admiring woodsman had presented, and then she chewed vigorously and slatted herself about in a tough manner. He sighed and went away muttering.

He ventured another and a last sortie, as if he wanted to make an end of his doubts. He also made a sensation.
