"Not so bad when you get used to 'em," answered Saul, lighting a fresh cigar. "But I know how you feel; I 'm just that queer about morgues. Can't get used to 'em nohow. Get the creeps every time I step inside a morgue. But then I don't hanker after murder work of any sort like some of the boys. It would be just my chance to get a taste of it before I 'm done with the Riverside robberies."

"What are the Riverside robberies?" inquired Donaldson, with a faint remembrance of the name.

"You been out of town?"

"No, but I don't read the papers much."

"I should say not. Four hold-ups in three weeks, all within half a mile of one another on Riverside Drive."

"Riverside Drive?"

He remembered now. The Arsdale home was near Riverside Drive. Barstow had spoken of these crimes.

"You on the case?" he asked indifferently,

"Yes," answered Saul. "I 'm on the case and if another one breaks, the case and the Chief will be on me."

The cab had stopped before an unlighted store. The street light revealed a window filled with a medley of china, teas, silks, and joss-sticks. Above, in big gilt letters, was the sign "Wun Chung and Co."
