Steve Levi has spent more than 40 years researching and writing on Alaska history. He specializes in the ground-level approach to history. A good example of his in-the-weeds approach is Bonfire Saloon, a saloon-level book of authentic Alaska Gold Rush characters in a Nome saloon on March 3, 1903. His book, The Human Face of the Alaska Gold Rush, is a compendium of people and events that are usually left out of scholarly books. For fiction, he specializes in the 'impossible crime,' where the detective must figure out how the crime was committed before he can go after the perpetrators. In The Matter of the Vanishing Greyhound, the detective must determine how a Greyhound bus can vanish off the Golden Gate Bridge and, in The Matter of the Departed Diamonds, how $3 million in diamonds can disappear from a locked bank vault.
