"The electric light is only needed at night."
"Do you recognize this knife?" and Penfield held it before her as he spoke. Kathleen's eyes did not shift their gaze, but her teeth met sharply on her lower lip.
"I see that it resembles one that I have," she said.
"You still have yours?"
"Yes, you will find it in my desk drawer at home."
"Had you only the one knife, Miss Whitney?"
"I may have had others," indifferently. "I do not recall; I buy my painting and modeling supplies as I need them."
The coroner replaced the knife without further comment.
"You use azurea perfume, do you not?" he asked.
"Yes."
