Writing biographies is a dangerous business. Autobiographies should be the easiest to write but end up as a pack of lies as authors want to present life according to their wishes instead of the truth. Unauthorized biographies don't have access to all the facts and end up gossip mongering and stating the obvious. And then there are authorized biographies which combine the worst of both the ones mentioned before.
Sir Arthur Conan Doyle is remembered for his stories of Sherlock Holmes and the Lost World. A new biography tries to reconcile these seemingly highly logical writings with his unshakeable belief in fairies and the supernatural.
