The interruption was from Mrs. Jones, called out through the nearly closed door of her parlour. Alletha, making no response, looked fit to die.

"Have you come to arrest me?" she whispered.

"Well, it's about it, Miss Rye. Apprehend, that is. We'll get a cab and you'll go in it with my friend there, all snug and quiet. I'm vexed that young Yorke should just be at home. Tried to get here half an hour earlier, but--"

Mrs. Jones's door was pulled open with a jerk. To describe the aggravated astonishment on her face when she saw the state of affairs, would be a work of skill. Alletha with a countenance of ghastly fear; Mr. Butterby whispering to her; the policeman on the door mat; Roland Yorke looking leisurely on.

"Well, I'm sure!" exclaimed Mrs. Jones. "What may be the meaning of this?"

There could be no evasion now. Had Alletha in her secret heart hoped to keep it from her tart, condemning, and strong-minded sister, the possibility was over. She went down the few steps that led to the room, and entered it; Mr. Butterby close behind her. The latter was shutting the door, when Roland Yorke walked in, taking French leave.

Which of the two stared the most, Mrs. Jones or Roland, and which of the two felt inclined to abuse Mr. Butterby the most, when his errand became known, remains a question to this day. Roland's championship was hot.

"You know you always do take the wrong people, Butterby!"

"Now, young Mr. Yorke, just you concern yourself with your own business, and leave other folk's alone," was the detective's answering reprimand. "I don't see what call you have to be in this here room at all."

In all the phases of the affair, with its attendant conjectures and suspicions, from the first moment that she saw John Ollivera lying dead in her house, the possibility of Alletha's being cognisant of its cause, much less connected with it, had never once entered the head of Mrs. Jones. She stared from one to the other in simple wonder.
