Vivianna Valentine Goes Up the River

After Viviana Valentine became a PI and partnered with Tommy Fortuna in their Manhattan business, wealthy debutante Tally Blackstone moved into Viviana’s position as secretary. The firm’s newest client, Buster Beacon, is one of Tally’s acquaintances. A scientist with a sprawling estate in Tarrytown, Buster has been hearing creaks and ghastly sounds in the house and asks the PIs to uncover the cause. When Tommy and Viviana arrive, they find a house full of scientists and wealthy investors, but Buster doesn’t know whom to trust. Within a day, an undercover FBI agent is dead, and the estate is snowed in with a bridge out. Although the investigators try to keep their identities secret, it isn’t long before they have to dig into top-secret Cold War scientific experiments in hopes of uncovering a spy as well as a killer.
