fore, the assistance of the police authorities, Manning
proposed to make a tour of the so-called houses of pleasure, which
infest all cities, deeming it most likely that he would obtain some
traces of Duncan by that means. This proved successful in a comparative
degree, for in one of these places Manning found a gay young cyprian,
who recognized Duncan's picture immediately. A bottle of very inferior
wine at an exorbitant price was ordered, and under its influence the
girl informed the detective that Duncan had come there alone one
evening about two weeks prior to this time, and that she had accompanied
him upon a drive. They had become quite familiar during their short
acquaintance, and Duncan drank a great deal. On the following morning he
had left the house, and stated that he was going to leave the city that

gentleman was located in the business section of the city, and his
neatly arranged store was well stocked with goods of excellent quality
and apparently of recent style. On entering the shop, Mr. Griswold was
found perched on a table in the rear, his legs crossed, and with nimble
fingers was engaged in the manufacture of some of the articles of his
trade. He was a small, sharp-featured man, about forty, with a shrewd
though not unpleasant face, and as he came briskly forward to greet a
prospective customer, his countenance was wreathed in a smile that was
almost irresistible.

"Can I do anything for you this morning?" was the polite saluta
