Reader Reviews On Case of the Mad Doctor

A terrific adventure with a rich historical heart
- A. J. West, author of The Betrayal of Thomas True

The historical details are vivid and convincing and describe the horror and injustice of the slave trade without preaching or pretension. This is an excellent, thought-provoking read, which I thoroughly recommend.

I was utterly gripped by this novel, finishing it very quickly. It’s a wonderful exploration of setting and time period and covers some really challenging topics. We have a wonderful main character who is very easy to root for. I would love to read more from this author.

Inspired by a true story this book is quite riveting. The author writes a good tale of British colonialism and while it is sometimes disturbing it does have a few moments of humour. I loved how the good guy wins in the end and this is a book worth the reading time.

This was a really good book. It’s an unusual storyline & plot with a nice quick pace with the action. Nice character building. Essentially it is a good vs evil plot. Very well written.

★★★★

The Case of the Mad Doctor is a terrific slow-burn combination of historical fiction, true crime, and magical realism. While Ollenu is certainly an interesting and compelling character and the descriptions of colonial Jamaica are fascinating, what I loved most was Lennon’s choice to incorporate magical realism and local legends/beliefs into his tale.

★★★★

I enjoyed the criminal case plot line of this story. I like the fact that the good guy accomplished his goal in the end. I would read another book by this author.
