The door was of thin wood and could easily be forced, but the room below was filled with men. Presently the light below went out, and the place was in darkness. He guessed that it was because Hagn did not wish the light to be seen from the road; though it was unlikely that there would come any inquiries, he had taken effective steps to deal with the police car which he knew would follow.
They had not taken his matches away, and Dick struck one and looked round. Standing before a fireplace filled with an indescribable litter of half-burnt papers and dust, was a steel plate, with holes for rivets, evidently part of a tank which had not been assembled. There was a heavy switch on the wall, and Dick turned it, hoping that it controlled the light; but apparently that was on the same circuit as the light below. He struck another match and followed the casing of the switch. By and by he saw a thick black cable running in the angle of the wall and the ceiling. It terminated abruptly on the right of the fireplace; and from the marks on the floor, Dick guessed that at some time or other there had been an experimental welding plant housed there. He turned the switch again and sat down to consider what would be the best thing to do. He could hear the murmur of voices below, and, lying on the floor, put his ear to the trap, which he cleared with a piece of wire he found in the fireplace. Hagn seemed to do most of the talking.
“If we blow up the road between here and Newbury, they’ll smell a rat,” he said.
“It’s a stupid idea you put forward, Hagn. What are you going to do with the chap upstairs?”
“I don’t know. I’m waiting to hear from Frog. Perhaps the Frog will want him killed.”
“He’d be a good man to hold for Balder, though, if Frog thought it was worth while.”
Towards five o’clock, Hagn, who had been out of the office, came back.
“Frog says he’s got to die,” he said in a low voice.

Two people sat in Dick Gordon’s study. The hour was four o’clock in the morning. Elk had gone, for the twentieth time, to Headquarters, and for the twentieth time was on his way back. Ella Bennett had tried desperately hard to carry out Dick’s instructions, and turned page after page determinedly, but had read and yet had seen nothing. With a deep sigh she put down the book and clasped her hands, her eyes fixed upon the clock.
