A Safe Place for Dying by Jack Fredrickson
An extortion letter arrives at Crystal Waters, one of Chicago's wealthiest gated communities. Shortly thereafter, a mansion blows up. The residents want answers fast before another zillion dollar residence turns to rubble. They hire former businessman Dek Elstrom. Ruined by scandal, Dek may be down, but thanks to his rather droll sense of humour, he is nowhere near out. A former Crystal Waters resident himself, Dek now lives in the primitive, pigeon-scented turret of a castle his grandfather never finished building. He still loves his ex-wife, and he wants to solve this case to redeem himself in her eyes. Sadly, he soon becomes the main suspect.
