Harry went to a corner drug store, and called Berger’s number. It would be easy enough to pretend that he had made a mistake, when Berger answered the phone. But there was no response.

Evidently Stanley Berger was not at home. So Harry lingered in the vicinity, while the day went by.

Working for The Shadow demanded patience. Long waits were not infrequent, but they were usually followed by moments of rapid action.

There was a hotel near the apartment house. Harry went there for lunch. In the lobby, he read the evening paper.

The death of Jonathan Graham now commanded very little space. This was the second day since the millionaire importer had plunged to doom from the window of his office in the Farworth Building. Suicide was the accepted verdict.

Harry called Stanley Berger’s number three times during the afternoon. He received no answer.

But at five o’clock, while he was walking past the apartment house, Harry noticed a young man enter the building. Believing that it was Berger, he watched the second-story windows. He saw a hand adjust one of the shades.

A light appeared in the apartment, later on. Harry maintained his vigil until seven o’clock, carefully watching all who entered the apartment house.

At seven o’clock, the light went out. Harry waited until his man emerged from the door of the apartment house. Then he followed, at a considerable distance.

Stanley Berger went to the same hotel where Harry had had luncheon. The man went in alone, and entered the dining room. Harry followed.
