Therefore I would shovel my stuff in heaps at the corners of the streets if I had enough for that; and as I haven't, I do my best by perfecting a really dependable detonator." Ossipon, who had been 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.

"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.
