A Green Knight (or is that a Knightess?) needs a PI to find her missing husband. Our Gumshoe gets the job of tracking down the charming Robert du Chasse. It also leads him back to one of the serious loves of his life. The trail leads to Robert who is holed up in a guest house in Little Carthage. But it's not long before a gunman bullet-holes the guest house and the PI finds his services are surplus to requirement. Is his only hope to spill the beans on Robert's love life?
