Alastair Gunn Books in Order

A series of London murders occurs at the same hour each Sunday in the weeks before Christmas. Leading her first murder investigation, Antonia Hawkins must identify the pattern and motive before the killer's precise schedule claims another victim.

Still recovering from an earlier attack, Antonia Hawkins takes charge of a murder discovered on Valentine's Day. As public scrutiny intensifies and an ambitious colleague challenges her authority, she must uncover the killer's purpose before more victims appear.

Bodies found in woodland suggest victims were beaten, deprived of food, and hunted before their deaths. Antonia Hawkins struggles to connect the apparently unrelated cases as evidence points toward a killer treating murder as a carefully controlled game.

Three men are discovered neatly arranged in an abandoned London flat, with no visible injuries or obvious cause of death. Antonia Hawkins must determine what connects them and whether an apparent suicide pact conceals a threat to others.
