Tweedledum and Tweedledee (novel)

Tweedledum and Tweedledee is a 1967 British novel by Alec Coppel.

The Daily Telegraph said the novel had "some nailbiting moments" and "an ingenious nemesis".

It was written as a movie script. The script was optioned by Charles Matthau in the 1990s who said "Coppel is a master of suspense who can set up 12 plot points in a single scene. All it needs is to be contemporized." However the film was not produced.
