This is Elly Griffiths’ 11th Ruth Galloway novel and, neatly, it harks back to the first in the series, The Crossing Places, when DCI Harry Nelson gets a letter that seems eerily similar to a note he received two decades ago and it appears as though a notorious killer has returned. It’s the opening gambit in a story which takes both Nelson and Ruth on a treacherous trip down memory lane. But some memories are best left buried, aren’t they? A cracking read from an author at the top of her game. Read our full review here.
