The Teleportation Accident by Ned Beauman

Set against the backdrop of 1930s Berlin, this novel follows the misadventures of Egon Loeser, a hapless and self-absorbed stage designer obsessed with recreating a 17th-century teleportation device. As he navigates a world teetering on the brink of World War II, Loeser's quest for love and professional success takes him from the decadent cabarets of Berlin to the intellectual circles of Paris, and eventually to the burgeoning film industry in Los Angeles. Along the way, he encounters a cast of eccentric characters, each embroiled in their own peculiar pursuits, all while the looming specter of historical events unfolds around them.
