Tea From An Empty Cup by Pat Cadigan

In a near-future, noir-inflected world dominated by immersive entertainment, a private investigator is drawn into a case when a young woman disappears after frequenting a virtual-reality parlor; what begins as a missing-person inquiry unravels into a darker mystery that blurs the line between flesh-and-blood life and simulated experience. The novel follows his sleuthing through seedy clubs, corporate interests, and the intimate lives of addicts who prefer carefully curated virtual selves, using the investigation to probe themes of loss, identity, memory and the addictive lure of living inside someone else’s constructed reality.
