A holiday on the picturesque island of Alderney leads to a case of cold-blooded murder for American Anglophile Dorothy Martin.

When Dorothy Martin and her husband, retired police detective Alan Nesbitt, decide to visit the beautiful island of Alderney in the English Channel, they hope for a pleasant, peaceful holiday.

And then they unearth some most disquieting revelations...
