"The side door was unlocked?"

"Yes, and that surprised me for a moment."

"Was your sister here at the time?"

"She was in the yard—she came in a moment later."

Godfrey and I exchanged a glance, which Miss Kingdon intercepted.

"Wasn't she in the yard?" she demanded. "What is this mystery?"

"We'll tell you in a moment," said Godfrey; "but please let us hear your story first. You had been, you say, at the Lawrence house?"

"Yes; Mrs. Lawrence has been very nervous since Marcia disappeared. I had been sitting with her until she went to sleep. I met Mr. Lester there earlier in the evening," she added, and cast me a half-mocking glance.

"Yes, he told me," said Godfrey. "He's been having an exciting time to-night. Were you with Mrs. Lawrence last night?"

"Yes; I spent the entire night with her."
