A Gravely Troubling Discovery

Volume 5 in The Dinner Lady Detectives series.

Margery and Clementine Butcher-Baker have been warned not to interfere in any more police investigations. When a body is found under Summerview School's playground during renovations, they have absolutely no intention of getting involved.

Instead, the pair agree to help Mrs Redburn, who suspects her husband of having an affair. But when their sleuthing sends them stumbling into the middle of the playground mystery, staying out of the police's way is impossible.

Can the Dinner Lady Detectives uncover the truth about the body, and solve Mrs Redburn's case, or will they end up digging their own graves?
