"Where's the boss?" casually demanded the officer. "He went over to Germany a couple of months ago," volubly explained Timmins. "I'm cock o' the walk for a few months now. Drop in and see me, on the d. q."

Two hours later, from a dark angle opposite, Officer McNerney saw Emil Einstein, with swinging steps, cigar in mouth, speed along eastwardly.

In plain clothes, his brow covered with a soft hat, the athletic policeman dashed along, keeping his prey in view. The lightning change of uniform gave him a clear protection, and in the thirty minutes of his necessary absence, the mustache which was McNerney's pride had disappeared.

"Either he goes to his girl, or else to meet the woman of the carriage," mused the man, who had sworn to reach a portion of the now heavily increased award. "Once I locate his 'stamping ground,' I am on the road to success."

It was twenty minutes before the excited McNerney saw Einstein slacken his determined pace down the Bowery. McNerney's heart beat, in wild hopes, as the lad, with furtive glances around, began to linger around the corner of the Dry Dock Bank.

"Is it the ten dollars burning in his pocket?" murmured the excited man. "Some cheap woman foolery?"

His practiced eye soon told him of the lad's determined purpose. For, in all the hovering movements, the office boy never left one or the other front of the bank building.

And none of the loungers, no street waif, no bedaubed siren lingered in colloquy there in the shadows of the respected fiduciary institution. "It's a poor fishing ground for the fancy," growled McNerney, as he suddenly darted forward in pursuit.

A woman, whose gliding walk and shapely voluptuousness of body indicated the Polish Jewess, paused, and bending her head, without a word of salutation, listened to the eager lad. The hands of the two met, in the darkness, and then Einstein sped back into the glaring Bowery, while the dark-robed woman pursued her way toward the East River.

"No bad walker," was McNerney's forced conclusion, as he gathered himself. The unknown had swept around the corner from the south and turned eastwardly to meet the waiting lad, with the sure gait of one who knew she was waited for.
