2010年，一位病人在作者David Sellu的照顾下去世。接下来发生的一系列事件现在提起让人会觉得不可思议，但导致David被起诉以及被判入监牢。 他的执照被撤回，他的事业就此结束。之后才被发现他的审判非常不公平，被种族歧视而干扰。最后，他赢得他的上诉，现在是自由身，但他的名誉以及事业已从次被摧毁。

这是他用他自己的声音，说出他的故事。

关于作者：

David Sellu跟他的家人住在英国伦敦。他曾经拥有来自 Manchester的医学执照，现在是一位退休的医学顾问。他现在大部分时间会去世界各地的医学院演讲，分享自己的经验。他希望可以透过他的经验去帮助未来其它的医生。

好评：  

It is welcome news that judges have found David Sellu was wrongly convicted of gross negligence manslaughter. Many in the surgical community were greatly concerned by the case. --Royal College of Surgeons

Did He Save Lives? is a hard read but utterly unputdownable (unless, like my wife and secretary, you are screaming in anger at the injustice of it all). It is of such importance that it should be compulsory reading for both patients and anyone contemplating becoming a health professional. --The Royal College of Surgeons

This is a troubling indictment of British justice, an institution many of us believe to be the best in the world, but this case shows clearly how fallible it can be and it chronicles the harm done to innocent people. --Doctors for the NHS
