Blenkiron said he was not surprised at the leakage, for there's always a lot of people who hear things they oughtn't to.

Leakages occurred every week, and the business was managed by people who knew their way about, for they avoided all the traps set for them, and when bogus news was released on purpose, they never sent it.

A convoy which had been kept a deadly secret would be attacked at the one place where it was helpless.

A carefully prepared defensive plan would be checkmated before it could be tried.
