They had reached Grand Central Station, and, luckily, had to wait only ten minutes before boarding a train for Delmore Park. During the short journey Britz fell into one of his deep silences, from which Greig did not disturb him until the train drew into the Delmore Park station.

Lieutenant Britz was too experienced a detective to rush unprepared into the home of the Collinses in the hope of obtaining incriminating evidence. In fact, he had determined not to visit the Collins house, but to devote himself to ascertaining something about the life and habits of the man whose name figured so conspicuously in the present stage of the investigation.

It was seven-thirty when the two detectives entered the home of the village postmaster and revealed their identity. The postmaster, a middle-aged, heavy-set man, appeared tired after his day's work. He was familiar with all the gossip of the wealthy residents of the park, and he quickly found new energy when the opportunity to display his knowledge was offered.

"That man Collins is a no good fellow," he confided glibly. "Just a bum—that's all he is. Stays out all night and sleeps all morning. His wife is a fine woman and I don't see how she stood for him all this time. Six weeks ago everybody around here knew that they had separated. She went to her brother's house—Lester Ward. But last night they seemed to be reconciled again. I saw Ward and Collins and Mrs. Collins at the station together and I heard them say they were going to the opera. That was the first time I'd seen Collins and his wife together since they separated. And this morning the postman told me that Mrs. Collins had spent the night in her own house—that she and her husband evidently had decided to live together again."

The postmaster paused reflectively, as if trying to read the meaning behind this unexpected reunion of the Collinses.

"Did you hear what brought about the break six weeks ago?" asked Britz.

"No, we had a lot of excitement around here just then," said the postmaster, his lips curling into a reminiscent smile. "That was the day of the robbery—or the attempted robbery." Aware that his visitors had begun to display increased interest, he proceeded with more deliberation, as if trying to heighten their curiosity. "The night before the Collinses separated, or about two o'clock that morning I should say, a fellow tried to break into the post office. Luckily there was a meeting of the lodge that night and a sociable after it. On the way home, Hiram Barker and Syd Johnson passed the post office just as the robber was forcing the door. They landed on him and took him to the lock-up. I notified the post office people down in New York and he was taken there for trial."

"Well, what happened?" Britz asked.

"The newspapers didn't seem to take much notice of the case," replied the postmaster regretfully. "A paragraph or two was all they gave it. A week ago the fellow pleaded guilty and was sentenced to two years and six months in the Atlanta prison."

"What was his name?" inquired Britz.
