Requiem for Mr. Busybody by Josh Lanyon

“Maybe you’ll be next, Mr. Busybody!”
From well-respected investigative journalist to resident busybody.
When former crime reporter Michael’s elderly friend Maurice suddenly disappears, he fears the worst. But Michael is unable to investigate, and no one is taking his suspicions seriously—least of all Nico, Maurice’s too slick, too smooth, possibly guilty boyfriend.
The only person Michael can think of who might listen is Leonard Drake, now a Lieutenant Detective with NYPD.
In fact, this excuse to contact his ex might just be what Michael has been waiting three years for.
