The emeralds of Suliman are stolen in North Africa and brought to London.

But the "mamba" (Mr JG Reeder) sets out thwart the thieves' plans as he hounds a notorious gangland villain...

Read by David Horovitch

Mr JG Reeder's novel methods bring the criminals of 1920s London to justice.

Created by Edgar Wallace, he is a uniquely English detective. An apparent fuddy-duddy working in some obscure capacity in the Public Prosecutor's office, he actually has a razor-sharp intellect and is a super-sleuth.

Mr JG Reeder solves his mysteries because he fully understands the "criminal mind".

Abridged by Neville Teller.
