en mentally swimming in deep waters, seized upon the
last word as if it were a saving plank.

"Yes. Your detonators. I shouldn't wonder if it weren't one of your
detonators that made a clean sweep of the man in the park."

A shade of vexation darkened the determined sallow face confronting
Ossipon.

"My difficulty consists precisely in experimenting practically with the
various kinds. They must be tried after all. Besides--"

Ossipon interrupted.

"Who could that fellow be? I assure you that we in London had no
knowledge--Couldn't you describe the person you gave the stuff to?"

The other turned his spectacles upon Ossipon like a pair of searchlights.

"Describe him," he repeated slowly. "I don't think there can be the

very closely. He was regularly married, you know. I suppose it's with
her money that he started that shop. Seemed to make it pay, too."

Ossipon paused abruptly, muttered to himself "I wonder what that woman
will do now?" and fell into thought.

The other waited with ostentatious indifference. His parentage was
obscure, and he was generally known only by his nickname of Professor.
His title to that designation consisted in his having been once assistant
demonstrator in chemistry at some technical institute. He quarrelled
with the authorities upon a question of unfair treatment. Afterwards he
obtained a post in the laboratory of a manufactory of dyes. There too he
had been treated with revolting injustice. His struggles, his
privations, his hard work to raise hi
