The Delaney family love one another dearly - it's just that sometimes they want to murder each other . . . Joy Delaney and husband Stan have done well. Four wonderful grown-up children. A family business to envy. The golden years of retirement ahead of them. So when Joy Delaney vanishes - no note, no calls, her bike missing - it's natural that tongues will wag. How did Stan scratch his face ? And who was the stranger who entered and suddenly left their lives ? What are they all hiding ? But for the Delaney children there is a much more terrifying question: did they ever know their parents at all ?
