Alibi - 39 (New Ed.)

As is often the case, Roger West of Scotland Yard is suffering from both overwork and family difficulties.

Whilst normally in full control, upon this occasion he insults an important witness.

This has the effect of nearly ruining his career, but then leads to the possibility of riches beyond his wildest dreams, and those of any honest policeman.

There is a conspiracy at work and it is up to West to solve this and all of his other problems.
