Hanna Wren

Hanna Wren writes contemporary suspense built around an inexperienced investigator learning to trust observation and judgement. The Deadliest Lead introduces Jenna Stack, a criminology student whose work with a high-end pet-sitting service draws her into a dangerous New York mystery after a routine dog walk goes wrong. Jenna must interpret competing advice from a professor, a client, a hacker, a police officer, and a federal agent while deciding which apparent allies deserve confidence. Wren identifies the novel as the opening volume of the Jenna Stack Mysteries. Planned continuations include A Dangerous Favor and The Bell River case, extending the central character's growth across connected investigations. The first book mixes action and intrigue with flashes of humour rather than presenting Jenna as a fully formed professional from the start. Its clearest authorial interest is practical learning under pressure, as academic knowledge becomes useful only when Jenna can assess people, evidence, and her own reactions in uncertain circumstances.
