GROWING TRUST

An O'Malley Investigations Collection — Books 7–9Chicago, 1925. They'd stake their lives on each other. Their hearts are another matter.

Kit Ashworth and Paddy O'Malley have survived gang wars and glittering frauds. But the cases that test a partnership hardest aren't the ones with a body in the parlor—they're the ones that make two people admit how much they've come to need each other. As Chicago reels from the O'Banion killing and the machine tightens its grip, the line between professional and personal is getting harder to hold.

The Last Toast — A society matron drops dead at her own charity luncheon, and every guest in the room had a reason to want her gone. Only Kit can move through this world of poisoned pleasantries—and only Paddy notices the moment she stops being just his partner in his eyes.

Pay the Piper — A corrupt alderman refuses to pay his blackmailer, and pays with his life instead. The trail runs straight into the heart of the Chicago machine, right as a familiar enemy pins on his badge again. Detective Walsh is back, and this time it's personal.

Two for the Show — Murder stalks the vaudeville houses, where protection rackets bleed the theaters dry. The case is dangerous enough—until Kit's former fiancé walks back into her life, and Paddy discovers that jealousy is a far sharper blade than any he's faced on the street.

Three cases. A poisoner in pearls, a killer in City Hall, and a ghost from Kit's old life—each one drawing Kit and Paddy closer to a truth neither is ready to say out loud.

Perfect for readers of historical mystery, Prohibition-era noir, and slow-burn detective partnerships. Three full novellas in one collection.
