That was certain.

But there were many things that were far from certain.

What had happened when Kitely revealed himself as a man who had been a witness of their conviction in those far-off days?
How had he revealed himself?
Had he endeavoured to blackmail them?
It was possible.
But there was still more to think over.

How had the dead clerk, Stoner, got his knowledge of this great event in the life of his employers?
Had he got it from Kitely?
That was not likely.

Yet Stoner had written down in his pocket-book an entry which was no more and no less than a _precis_ of the absolute facts.
