When Blosberg reached the roof he had replaced the trapdoor, but he wasted no time, and began looking for a means of descent. He still held a gun in his hand and whirled sharply as the trapdoor suddenly flew open. He saw Jack at the same moment Jack saw him, and both fired.

But the aim of each was poor and Jack followed his shot by leaping to the roof. Then he dropped down suddenly as Blosberg fired again, and, still unharmed, drew himself quickly behind a chimney nearby. Blosberg took refuge behind a second chimney.

Now Lord Hastings' head appeared and drew back suddenly as Blosberg took a quick shot at him.

"All right, sir, come on!" called Jack. "I'll get him if he tries to pot you again."

Lord Hastings sprang through the opening and a moment later Frank also appeared on the roof. Blosberg made no effort to fire again, apparently realizing the hopelessness of his case.

Frank and Lord Hastings now had taken their places with Jack behind the chimney.

"Well, we can't fool around here all day," said Jack. "We'll circle about and one of us can get him."

Lord Hastings, wounded, was left behind the chimney, while Frank, who had produced another revolver, leaped out suddenly to the left, Jack at the same time springing to the right. Then they moved forward.

"Hold on," came Blosberg's voice at this moment. "I surrender."

The three friends breathed easier.
