Spare Man, The by Mary Robinette Kowal; 2022. Softcover.

Hugo, Locus, and Nebula-Award winner Mary Robinette Kowal blends her no-nonsense approach to life in space with her talent for creating glittering high-society.

In this stylish sci-fi mystery, The Spare Man, Tesla Crane, a brilliant inventor and an heiress, is on her honeymoon on an interplanetary space liner, cruising between the Moon and Mars. She's traveling incognito and is reveling in her anonymity. Then someone is murdered and the festering chowderheads who run security have the audacity to arrest her spouse. Armed with banter, martinis and her small service dog, Tesla is determined to solve the crime so that the newlyweds can get back to canoodling--and keep the real killer from striking again.
