“If I could put my hand on one of my own men, I wouldn’t trouble you, but there is no time, and delay is dangerous.”

A hasty hand-shake to Sheila, a fond lover’s look into her eyes, and Wingate was out of the post-office, and into a taxi, en route for Victoria.

He thought of her all the time he was travelling to Brighton. In these last few days her great sorrow had brought her very near to him. He had read her disappointment when Smeaton had forbidden her to accompany him. But she would not resent that on him; she knew he was working in her interests, that his one thought was to help in solving the tragic mystery that was clouding her young life.

The train arrived at Brighton punctual to the minute, and mindful of Smeaton’s remark that delay was dangerous, he drove straight to the post-office.

He was, in a certain sense, elated with the mission that had been entrusted him, through the mere accident of Smeaton not having had time to put his hand on an experienced man. But he felt some trepidation as he walked through the swing-doors. Surely people who set forth on detective work must have nerves of steel and foreheads of triple brass.

He bought some stamps first, not because he wanted them, but in order to screw up his courage to sticking-point.

A sharp-featured, not too amiable-looking young woman served him. When he had completed his purchase, he asked in as cordial a voice as he could assume:

“Are there any letters or telegrams for the name of Herbert?”

The young woman regarded him with a suspicious glance.

“Is your name Herbert, may I ask?”
