The Dead Letter

This is a very interesting detective story. It's classic murder-mystery, with plenty of twists and turns.
I was staking my guess of who the murderer was pretty early on, but the evidence kept going other directions...I won't say whether I was correct in my guess or not! :)
The only reason I'm not giving five stars is because I personally don't agree with the use of putting anyone in a trance to help solve a murder, whether it is or is not successful. I know there's a power is hypnotism, and I don't enjoy getting the creeps from reading about people using it.
