Still the man crouched low, his eyes now fixed in agonised expectation on the tank.

The man on the roof heard the clocks of Daneford strike eleven. Just then the tank trembled, swayed a moment, then shot downward with a roar. Up the hole made by it danced a cloud of flame.

The man on the roof sprang to his feet, and with a shout leaped on the parapet crying:

"Help! Help! For God's sake, help!"

With that tank the evidence against him had vanished.

A groan came up from the people below, and then a cheer.

"The fire-escape is coming. Have courage!"

Shading his eyes with his hands he looked in the direction of the lodge, and saw approaching by the carriage-way the fire-escape.

"Help! Quick!"

"Courage, Wat! We will save you!"
