Away With Them To Prison

Description for AWAY WITH THEM TO PRISON by Sara Woods:

Antony Maitland's old friend Inspector Mayhew and a young constable had all the evidence to arrest two seedy salesmen for running a protection racket and killing a shopkeeper. The case against them appeared watertight when they brought it to trial. But suddenly a stunned courtroom heard the witnesses completely change their story and swear that the police had rigged the evidence and extorted money from the accused! Scotland Yard was in an uproar, their reputation tarnished...unless Maitland could find a flaw in this perfect frame-up and uncover the most shocking villain of his career.

This is #44 in An Antony Maitland Mystery.
