The Unicorn Heist. Lowan, #18

Meet Lowan, a telepathic alien working as a private detective in the 1930s. Museum fundraiser galas are supposed to be uncomfortable clothes, hors d'oeuvres, and awkward speeches. This one adds murder, arson, and high-stakes thievery. Lowan has been hired to advise on security for the unicorn staff - a glittering, bloodstained curiosity worth fortunes - and what should have been an easy job explodes into the worst event in the museum's history.
A brutal killer called Poseidon escapes police custody with a single aim: to reclaim what was taken from him. And he's not the only one trying to steal it. Joined by Marx, Tom, and Rita, Lowan finds himself caught in the middle of three conflicting heist plans. Lowan's fragile telepathic edge becomes the only map through panic and violence. Lowan and his team face an escaped killer, sabotaged exits, a maze of shadowy basement passageways, accidental arson, and a rooftop fight over an ancient relic.
Can Lowan expose the impostors and stop a monstrous thief before the gala turns into a slaughter?S. E. Grosskopf's writing is strongly influenced by the old pulp fiction magazines and Golden Age radio dramas of the 1930s-1950s. If you like fast-paced action and mystery with a dash of urban fantasy and quirkiness, then you'll love these books. This is the eighteenth book in the series. The books follow chronologically.
