Joe Gores' DKA novels are in the CU through a story where Dan Kearney met the ghost of the Continental Op. In this DKA book, a couple of cops receive help on a case from an L.A. Homicide detective named Harry Bosch. Bosch is featured in a series of novels by Michael Connelly. All of Connelly's novels take place in the same universe. Bosch has a cameo in Robert Crais' Elvis Cole novel The Last Detective, while Cole cameos in the Bosch novel Lost Light. Like Connelly, Crais sets most of his novels in the same universe. Bosch also cameos in Paula L. Woods' Charlotte Justice novel Strange Bedfellows. Finally, in the story "Red Eye" in the all-crossover anthology FaceOff, Bosch meets Dennis Lehane's Boston P.I. Patrick Kenzie.
