The Murder Hypothesis is a gripping YA thriller by Sarah Wishart, perfect for fans of A Good Girl’s Guide to Murder. The story follows Grace, a science-obsessed teenager who moves with her father to a quiet village in Devon, seeking a fresh start after a tragic incident in London.

Their new home comes with a second-hand smart speaker that, at midnight, ominously declares: “I’m going to murder you.” Intrigued and alarmed, Grace investigates and uncovers four mysterious deaths in the village all officially deemed accidents. However, Grace suspects one was a murder.

Applying the scientific method, Grace formulates a hypothesis and gathers data, using charts, graphs, and Venn diagrams to analyze the evidence. As she delves deeper, she must identify both the victim and the killer before becoming the next target.

This novel combines a compelling mystery with STEM elements, offering a unique twist on the traditional whodunit.
