"Great Victorian mystery, but be warned, it is long"
This is a wonderful mystery, but just like his contemporary Charles Dickens, Mr. Collins writes a very long novel. Some may find this wearisome and should stick to 20th Century Pulp Fiction. Those willing to commit the time (nearly 21 hours in listening time) will find the effort worthwhile and the various readers add a dimension that make the length more than tolerable (my favorites are Gabriel Betteredge and Miss Clack)!
"Insight into a mysterious condition"
Although fiction, this story gives true insight into the life and thinking of a adolescent with high functioning autism. Mr. Haddon does a nice job of illustrating some of the core features of this disorder. I strongly recommend this reading to teachers and health care providers, in particular, who provide services to children with autism. It makes great reading for anyone, regardless.
