Cudahay tracks ghosts. Not the ethereal kind. The regret-dating-you-so-they-disappear kind. His partner, Serena, deals with the losers and their sob stories; he tracks down the rather-not-be-found to provide proof of life so the losers can move on.
When a real ghost from Cudahay’s past turns the tables and tracks him, however, Cudahay learns what stalking really means.
