A desperate for work Hetty takes Geoffrey up and down the streets and sidewalks of town advertising the foundering detective agency. This proves to be a wise method of business, as they pick up a client: a woman whose estranged son, Michael, who has been diagnosed with schizophrenia, lives in another town. Her husband, Reg, Michael’s stepfather, refused to have her son living with them as Michael grew more delusional. The mother wants to know how her son is doing. As Hetty investigates, she discovers that Michael has disappeared from his sheltered housing unit and has had a hard time being accepted by society. As it becomes clear that Michael has gone off his medicine, Hetty finds herself in a race against the clock to try and find the man before he hurts himself or others in his delusional state.
