1950, New York. Viviana Valentine—Girl Friday turned partner to New York’s top investigator, Tommy Fortuna—is drawn into a sordid new case when Buster Beacon, a wealthy man of science, beckons them to a party at his mansion north of the city. There, Buster entertains blue-blooded friends as well as investors keen to make a dollar on the many advancements made in his home laboratory, but he’s been hearing strange noises in the night coming from his expansive estate, and he doesn’t know who to trust. Once Viviana and Tommy arrive, the party is snowed in. And suddenly, there is a dead body and nowhere to hide. Who killed the disguised federal agent in their midst? And how have details from the top-secret lab become public? Once chomping at the bit to be brought into this mysterious life, Viviana wonders if she’s ready for the risks that come with the territory—risks that rise treacherously high as the killer targets the next victim. Set in the gritty noir world of 1950s New York City, Emily J. Edwards’s Viviana Valentine Goes Up the River packs all the elements mystery fans love: an irresistibly clever protagonist, a posh cast of heroes and villains, and a murder case that could defy even the most seasoned investigator.
