I literally couldn’t put this one down. I wondered initially If Raywen was the one having a relationship with Felix and I also questioned given his attitude if Eddie was the killer. I thought from the start that this would be a murder mystery but the more the author went into Emily and Felix’s everyday routine and when she found the box amongst her fathers possessions it became clearer for me. I really did feel sorry for Ira Emily and Raewen at the ebb because they had no clue until they read the letter what had actually happened and had spent so many years going over what happened with no real answers. My only missing link was more around the estranged wife and the family that Felix had it would have been good to get more of a mental insight into Felix as he is portrayed as cold until you read the letter but it still doesn’t explain why he was the way he was and I felt that was the only thing missing from the story. Great book highly recommended
