Tom and Caroline Johnson chose to commit suicide 6 months apart. Anna, their daughter, is unwilling to believe it was suicide and is determined to find out what really happened. Murray Mackenzie, retired policeman, offers to help her. This book was a slow start and kept me guessing through a few plot twists until the surprise ending. It had lots of secrets and family drama. I liked the characters of Murray and his wife Sarah the best. The book also dealt with the theme of mental illness and handled the subject very well. I like Macintosh's writing and look forward to her next book.
