Meanwhile, the “Yellow Mark,” having gained a foothold on the crane...
...is now only a few metres from the ladder when it suddenly realizes that its retreat is cut off by the policemen climbing up to meet it...
The man seems to hesitate for a fraction of a second, then suddenly, in two bounds, he scrambles onto the roof of the engine cab.
There he is!!... Ah! Ah! He’s caught like a rat!... Go on, lads!!
Don’t triumph too soon, Kendall!...
Indeed, strangely motionless, the “Yellow Mark,” cornered on the narrow platform, seems to be awaiting the assault of his adversaries...
And suddenly, as they throw themselves upon him, an immense, blinding flash bursts from his body and knocks them all to the ground, unconscious!...

When, after the moment of bewilderment that follows this incredible phenomenon, the searchlights begin probing the darkness again, they come to rest on the fantastic figure perched atop the crane, holding aloft, at arm’s length, the lifeless body of a policeman!...

HAHAHA!!...
Good God! What are we to do?... The slightest false move, and it’s death for this poor fellow!...
Wait!!... I have an idea... I’m going to try something... Above all, let there be absolute silence!...
And Blake begins slowly climbing the narrow ladder, addressing the “Yellow Mark” in a calm and persuasive voice...
Hello, “Yellow Mark”!...
Listen to me!...
