He carefully examined the palm of her right hand, which was ungloved, then tried to remove the glove from the left, but in vain. He was obliged to rip it up with a pair of scissors. Afterwards he examined the hand minutely, giving vent to a grunt of dissatisfaction.

“Suspicious of foul play—very suspicious,” the doctor observed. “To-morrow we shall know the truth. She’s evidently a lady, and, by her dress, a foreigner.”

“She arrived by the Paris mail to-night,” the cabman observed.
