A wild, eager hope seized him.
Instantly he drew the blade of his knife across the membrane. An object slipped out.
It was rusty and corroded, but in the glare of the electric light it was not hard for him to recognize its character at once.
It was the metal case.
Stanhope held it up with insane gestures. Frank, Barney and Pomp saw and understood.
Instantly all started for the cabin of the submarine boat.
They were quickly aboard, and once the diving suits were off Stanhope yelled with glee:
“Hurrah! We have succeeded! Here is what will save the life of Valentine Tucker! It is an act of Providence!”
The corroded case lay upon the cabin table.
