An asexual detective investigates a gay polyamorous quad. The police suspect one of the quad, Raith Balan, of faking a painting. So do money launderers who sink profits into art. Mike, Ross and Phil, the three men in Raith's life, must prove his innocence. They're hampered by their certainty that a member of the Fraud Squad is corrupt. The senior investigating officer is Detective Sergeant Nick Seabrooke. He knows he is asexual, but is he aromantic too? As Raith's lovers struggle to keep Raith safe and find the fraudster, the sergeant struggles to understand why the quad is often in his thoughts.
