In seventy-degrees weather, his long coat and winter hat begs for Madison's curious mind to do a little snooping.Her curiosity uncovers a complex scheme almost twenty years in the making and inadvertently involves a new friend the teens have befriended. Drawn into the dark underworld of industrial secrets, corporate spies, and an upcoming trial, before week's end they'll face guns, kidnappings, and the unknown dangers of a swampy bayou.Back in The Sisters, Granny Bert and the self-proclaimed 'Senior Division' of In a Pinch Professional Service (aka The Geriatric Crew) take on a new client. When the temperamental Ella Getty proves to be almost too much for even her grandmother to handle, Madison helps solve yet another mystery when she gets back to The Sisters.
