This collection of cases takes the reader into the essentially private world of three general medical practitioners, all practising in England from the 1930s until the 1990s. Their backgrounds are very different, but they are linked because they all stood trial for murder, with motives ranging from the power over life and death, and a pre-occupation with social advancement and greed, to obsessive jealousy and paranoia. Each of these cases has attracted widespread public attention and been the subject of numerous publications and documentaries. This work approaches the subject of murder in an innovative way. Each case commences with a brief outline of the subject’s background, progresses to the criminal events, and culminates in details of the trial itself. This approach fully involves the reader rather than allowing them to remain as passive observers. This enables them to place themselves in the position of being a potential juror before being invited to consider their own verdict. Each of the cases concludes with an overview of the main aspects for the reader’s final consideration.
