With a picturesque black and white lighthouse, pebble beaches and stunning views of sea and mountains, the island of Anglesey off the coast of North Wales is the perfect place for an idyllic mid-summer painting holiday.
And watercolour artist, businesswoman, and amateur sleuth Penny Brannigan is enjoying the retreat enormously - until she discovers the body of a New Zealand journalist on a secluded beach just as the tide is going out, threatening to take the body with it.
The post mortem reveals the victim died from injuries "consistent with a fall from a great height," and the death is ruled accidental. But Penny thinks there's more to the story. Curious how the victim came to such an untimely end at this most inhospitable spot, she uncovers a link to a mysterious disappearance several years earlier.
And as her holiday romance with a wildlife photographer turns to love, she learns some truths about herself, too, that surprise her.
As the winds of change blow through Penny's own life, she sets sail on a friendly tide for a future she never dreamed possible, in a beautiful place she never imagined
