London, and Paris seem to be covered pretty well, so here's Tibet, New York, and Munich:
(This is what NoveList turned up)
The Skull Mantra by Eliot Pattison: "When a headless corpse turns up on a Tibetan mountainside, veteran police inspector Shan Tao Yun is released from prison to investigate the crime, and he quickly uncovers a conspiracy involving American mining interests, corrupt Party officials, and Tibetan sorcerers. Winner of the 2000 Edgar Award for Best First Novel."
Tibet: Through the Red Box by Peter Sis: "The author recreates his father's visit to Tibet and the wondrous things that he found there."
Straight into Darkness by Faye Kellerman: "A homicide inspector in 1920s Munich hunts for a serial killer."
Suspension by Richard E. Crabbe: "In the tense aftermath of the Civil War, the construction of the East River bridge becomes a target for a group of Southern partisans, led by a fanatical captain, as Detective Tom Braddock's investigation into a murder uncovers hints of the conspiracy and puts his own life in jeopardy."
The Broken Hearts Club by Ethan Black: "Detective Conrad Voort races against time to catch an elusive serial killer, an investigation that leads him to an informal group of men whose only connection lies in their unsuccessful love lives."
It's a bit heavy on the mysteries but I hope this will help!
