The Teleportation Accident by Ned Beauman
In the declining Weimar Republic, Egon Loeser works as a stage designer for New Expressionist theatre. His hero is the greatest set designer of the seventeenth century, Adriano Lavicini, who devised the so-called Teleportation Device for the whisking of actors from one scene to another - a miracle, until the thing malfunctioned, causing numerous deaths and perhaps summoning the devil himself. Apolitical in a dangerous time, sex-driven in a dry spell, Loeser leaves the tired scene in Berlin in pursuit of the lubricious Adele Hitler (no relation), who couldn't care less about him. Heading first to Paris and then to Los Angeles, he finds his entire tired Berlin social circle reconstituted in exile, under the patronage of a crime writer and his possibly philandering wife. He also finds himself uncomfortably close to a string of murders at Caltech, where a physicist, assisted by Adele herself, is trying to develop a device for honest-to-God teleportation.
