He woke up with a dead body in his bed, a killer in the shadows... and a wife who despises his very existence. Aris Thorne, a modern forensic genius, transmigrates into the body of Silas Vane—the wealthiest, most scandalous Viscount in the City of Twilight. Silas is famous for three things: his devastating looks, his absolute lack of magic, and his insatiable appetite for women—from the high-born Duchesses to the blushing maids in his own estate. The Problem? Silas is the prime suspect in a murder. To clear his name, he must use modern science to outsmart magical killers. The Complication? His estranged wife, the icy and powerful Lady Eleanor. She expects him to be a useless drunk, but the "New" Silas is sharp, dangerous, and inexplicably alluring. As Silas hunts the "Gallery of Sin" killers by day, he navigates a minefield of temptation by night. From the maid who knows too many secrets to the assassin sent to seduce him, Silas walks the razor's edge. "My Lord," the maid whispered, locking the door. "The Lady Eleanor is coming down the hall..." Silas smirked, buttoning his shirt. "Let her come. A detective thrives under pressure." Warning: Contains a smart protagonist, high-stakes mystery, heavy sexual tension, a cold wife, and a harem of women who can't resist a man with a brain.
