THE PHOTOGRAPH Allerdyke went off to Hull, post-haste, because of a telephone call which roused him out of bed an hour before his usual time.

It came from Chettle, the New Scotland Yard man who had been sent down to Hull as soon as the news of Lydenberg's murder arrived.

Chettle asked Allerdyke to join him by the very next express, and to come alone; he asked him, moreover, not to tell Mr.Franklin Fullaway whither he was bound.

And Allerdyke, having taken a quick glance at a time-table, summoned Gaffney, told him of his journey, bade him keep his tongue quiet at the Waldorf, wrote his hasty note to Appleyard, dressed, and hurried away to King's Cross.

He breakfasted on the train, and was in Hull by one o'clock, and Chettle hailed him as he set foot on the platform, and immediately led him off to a cab which awaited them outside the station.
"Much obliged to you for coming so promptly, Mr.Allerdyke," said the detective.
