A Gothic country manor, a doomed wedding, and a cowlicked criminal...
When someone sabotages a local couple's path to the altar, they need help ensuring their special day isn't ruined for good. It isn't long before retired spy Irma Abercrombie and resident sun-deprived nerd Violet Blackheart get roped into lending a hand sorting out the duo's wedding woes—and all the bodies.
Meanwhile, Violet preps for her business partner's island arrival—blender drinks at the ready—as Irma secretly tries to track down Violet's former CFO...and their company's former money. Along the way, Irma decides to mix business with pleasure, but struggles to sort out the rules for septuagenarian singletons who can dispatch bad guys with a handful of Tinker Toys, and are looking for a bit of romance in their downtime.
With her trusty telescoping mirror and adorable (if untrainable) canine companion Mr. P, along with nerdy sidekick Violet Blackheart, Irma sets out to save a wedding, retrieve Violet's fortune, and find a killer.
