Edgar Wallace 
Herbert Armstrong – Poisoner 

Major Herbert Rowse Armstrong has the dubious honour of being the only UK solicitor to be executed for murder. ‘Herbert Armstrong – Poisoner’ details the courtroom proceedings following his arrest, documented by then-reporter, Edgar Wallace. A grim, true-crime story, it follows two sets of poisonings, one of which proved to be fatal. A gripping account of a trial and the British criminal justice system at the time, this is a superb read for true-crime enthusiasts and fans of ‘The Salisbury Poisonings’ on Netflix.-
