CHAPTER XXXIV.
THE MYSTERIOUS DEATH IN PERCY STREET Miss Polly Burton had had many an argument with Mr.Richard Frobisher about that old man in the corner, who seemed far more interesting and deucedly more mysterious than any of the crimes over which he philosophised.
Dick thought, moreover, that Miss Polly spent more of her leisure time now in that A.B.C.shop than she had done in his own company before, and told her so, with that delightful air of sheepish sulkiness which the male creature invariably wears when he feels jealous and won't admit it.

"You would like to know who murdered that old woman ?" he asked at last.
"I would like to hear your views on the subject," Polly replied.
"I have no views," he said dryly.

"No one can know who murdered the woman, since no one ever saw the person who did it.
