Thea Osborne hopes to spend a quiet Christmas house sitting for the Shepherds in the picturesque village of Stanton. Walks in the local countryside with the dogs and perhaps a meal in the pub are all the excitement she wants. When her arrival at the village coincides with the funeral of local businessman Douglas Callendar, found electrocuted in his bath, Thea's interest is stirred but the onset of flu looks to prevent any sleuthing. However, when two people show up brutally murdered the following afternoon, even when battling a fever Thea finds herself thrust into the middle of yet another Police investigation.
