The Illusive Mr. Brown
25 December 2013 | by (Buffalo, New York) – See all my reviews

The Secret Adversary was Agatha Christie's novel which launched her Nick and Nora Charles characters of Tommy and Tuppence. This story shows how they met and the first case they got involved in.

It was back on the Lusitania in 1915 when both were passengers. Some other passengers on that ill-fated ship were involved in a lot of intrigue relating to the late World War. That's over now, but Toria Fuller during the chaos of those passengers abandoning the torpedoed ocean liner grabbed herself a piece of a secret treaty and has had it for lo these many years.

Now some Bolsheviks want it to stir up some revolution in the United Kingdom. There's a cell of them operating under the lead of the illusive Mr. Brown. British Intelligence knows about Brown, but no one knows who he is.

James Warwick and Francesca Annis as Tommy And Tuppence renew their acquaintance from the Lusitania and get themselves involved in the case as a pair of amateurs. They're needed because the Bolsheviks seem to know all the professionals. They prove to have a knack for solving mysteries.

A lot of this might seem melodramatic today, but Agatha Christie was a good observer of the times this was written in. The Russian Revolution had occurred and a lot of governments were pretty uneasy in their seats of power. Christie alludes to a General Strike and she turned out to be a prophet because one did happen in the UK in 1926 a few years after The Secret Adversary came out. It was real enough to the population in the United Kingdom back then.

The Secret Adversary is a good introduction to Tommy And Tuppence and proved to a pilot for a BBC series of their mysteries. Recommended for those who think Ms. Christie wrote about Hercule Poirot and Jane Marple exclusively.
