First Place Winner of the 2018 Chanticleer Mystery and Mayhem Historical Mystery Award and fourth book in the USA Today bestselling Victorian San Francisco Mystery series.

It’s the summer of 1880, and once again the lovely and inquisitive businesswoman, Annie Fuller, is helping San Francisco lawyer and fiancé, Nate Dawson, with a troublesome case. Nate’s client, a female typesetter accused of murdering her boss, refuses to help in her own defense. Complicating matters, Nate’s sister Laura insists on getting involved in the potentially dangerous investigation, while Laura’s friend Seth Timmons, troubled Civil War veteran, finds himself a witness for the prosecution.

Will Nate be able to win his first big case? Will Laura and Seth find some way of remaining friends? And finally, will Annie and Nate’s upcoming nuptials be derailed by their attempts to track down a killer?

Old friends and new readers alike will enjoy Deadly Proof, this fourth installment of the cozy, historical mystery series that blends light-hearted romance and suspense, while examining the lives of late 19th century women who worked in the printing trades. Deadly Proof is followed by Pilfered Promises and Scholarly Pursuits, and Locke’s shorter works, found in Victorian San Francisco Stories and Victorian San Francisco Novellas, feature minor characters from the series.
