Agatha Arch's life shatters when she discovers her husband in their backyard shed, in flagrante delicto, giving the local dog walker some heavy petting. Suddenly, Agatha finds herself face to face with everything that frightens her...and that's a loooooong list.

Agatha keeps those she loves close. Everyone else she keeps as far away as possible. So she's a mystery to nearly everyone in her New England town. To her husband, she's a saucy no-B.S. writer. To her Facebook Moms group, she's a provocateur. To her neighbor, she's a standoffish pain in the butt. To her sons, she's chocolate pudding with marshmallows. And to her shrink, she's a bundle of nerves on the brink of a cataclysmic implosion.

Defying her abundant assortment of anxieties, Agatha dons her spy pants - a pair of khakis whose many pockets she crams with binoculars, fishing line, scissors, flashlight, a Leatherman Super Tool 300 EOD, candy, and other espionage essentials - and sets out to spy on her husband and the dog walker.

Along the way, she finds another intriguing target to follow: a mysterious young woman who's panhandling on the busiest street in town.

It's all a bit much for timorous Agatha. But with the help of her Bear Grylls bobblehead, a trio of goats, and a dog named Balderdash, she may just find the courage to build a better life.
