Her cousin Gemma is desperate for help with her ailing mother before her imminent wedding, which Evelyn knew nothing about! Aunt Agnes in tow, she journeys to Scotland, expecting to find Malmo Manor in turmoil. To her surprise, her Scottish family has been keeping far more secrets than the troubled state of their matriarch. Adding to the tension in the house a neighbor has opened his home, Elderbrooke Park, as a retreat for artistic veterans of the Great War. This development does not sit well with everyone in the community. Is the suspicion towards the residents a catalyst for murder? A tragedy at Elderbrooke Park's May Day celebration awakens Evelyn's sleuthing instinct, which is strengthened when the story of another unsolved death emerges, connected to her own family. What she uncovers on her quest to expose the truth will change several lives forever, including her own.
With the shadow of history looming over her, Evelyn must trust in her instinct and ability to comb through the past to understand the present, before the murderer can stop her and tragedy strikes again.
