"I endeavored to do so. I took the syringe away from her."
"You took it away from her after she had taken nearly all of the dose?"
"She had taken all but five minims before I could reach her."
"It was you who sent the nurse away, I believe?"
"I gave her permission to go out."
"You told her to remain until nine o'clock?"
"I told her that she might do so."
"And this syringe incident occurred at eight o'clock?"
"At eight thirty."
"That is, half an hour before you expected to be interrupted by the return of the nurse?"
