The body of a man lies half-hidden in the purple heather, stabbed to death on the
North York Moors. Detective Sergeants Nina Featherstone and Hazel Fuller set out
to discover his identity and locate the mystery woman who accompanied him on the
Coast to Coast Walk before disappearing without trace. When another body is found
on a rifle range near Catterick, they begin to suspect a military connection.
While Mills assists with the forensic evidence, she remains preoccupied with another
investigation – to discover who shot the red kite and left poisoned bait on the moor
that nearly killed Earl.
