The brief

Pip Fitz-Amobi questions the accepted account of Andie Bell's death, choosing the case as the focus of a school investigation.

Sal Singh's presumed guilt gives the town a convenient conclusion, but Pip notices reasons to examine the evidence again.

Interviews and project material make the investigation visible, allowing readers to follow competing explanations alongside the protagonist.

As private secrets emerge, a harmless academic exercise becomes a source of pressure from people who prefer the past to remain closed.

The opening series novel combines detective work with questions about reputation and who gets believed; the culprit and ending remain undisclosed here.

Key ideas worth keeping

Accepted stories still need evidence.

Reputation can distort an investigation.

Curiosity creates responsibility as well as risk.
