Knots and Crosses: An Inspector Rebus Novel by Ian Rankin and really enjoyed it! It's about a detective in Edinburgh, Scotland who went through a traumatic time in the armed forces and is still getting over it. He has a brother who is a hypnotist, an ex-wife who lives with his Captain's son, and Rebus' daughter lives with them.
When Rebus gets strange letters delivered and gets on the case of murders with knots - he has to figure out who the mysterious killer is... It's full of interesting characters and I highly recommend it. - Rob
