In a future where murder is commonplace, Custodians are law enforcement officers who solve crimes by invading the minds of suspects.

Madness lurks in the damaged spaces of that mind — and the Custodian's cohesion depletes the longer they stay. Find the truth before what remains of the suspect's sanity destroys yours.
