Mystery: body in back body in front

[Jim]

I need the title/author of a mystery in which a guy buries the body of his tormentor far back in his rear garden. He lives for years worrying about his secret. Then ... a body is discovered in his Front yard!

Jim, around what year did you read this book? This will help us narrow down the search.

Can you tell us more about the guy and his tormentor - e.g., their ages, jobs/students/skills/interests, etc.? Does it start when they're kids/teens?

Does the story feature a detective/private investigator?

What is the story's time period and location (country/region/city/small town)?
