"Just as plain as what he's told," said the other Gaffney. "I followed him down the street; he walked one side, I t'other side. He went into Clytemnestra House--one of those big houses of business flats and offices--almost at the bottom. I waited some time to see if he was settled like, or if it was only a call he was making. Then I went into the hall of Clytemnestra House, as if I was looking for somebody. There are two boards in that hall with the names of tenants painted on 'em. But there's not that name--Gerald Rayner. Still, I'll tell you what there is, sir--there's a name that begins with the same initials--G.R." "What name?" asked Appleyard. "The name," replied the second Gaffney, "is Gavin Ramsay--Agent." CHAPTER XVII 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. "And for coming by yourself--that was just what I wanted." "Aye, and why?" asked Allerdyke. "Why by myself? I've been wondering about that all the way down." Chettle, a sleek, comfortable-looking man, with a quiet manner and a sly glance, laughed knowingly, twiddling his fat thumbs as he leaned back in the cab. "Oh, well, it doesn't do--in my opinion--to spread information amongst too many people, Mr. Allerdyke," he said. "That's my notion of things, anyway. I just wanted to go into a few matters with you, alone, d'ye see? I didn't want that American gentleman along with you. Eh?" "Now, why?" asked Allerdyke. "Out with it!"
