Blackwater Lake

Matthew Stanyer's childhood was not a happy one due to his mother's compulsive hoarding. Now as an adult he's still reluctant to return to the house but his mother's dementia is getting worse. After not hearing from his father for several days after he said he'd call, Matthew goes to their house and finds a note from his father saying he and his wife can't go on this way. The police find their bodies near Blackwater Lake and their deaths are ruled a murder-suicide. Now Matthew has the daunting task of going through the mountains of his mother's hoard. He's taken back to their past - one neither parent ever spoke of - and discovers what may have started his mother's hoarding and why his father chose Blackwater Lake to end their lives.

A quick read with some twists and turns.
