From Sir Peter's much younger nurse turned fiancé, his wayward combative son to his ex-wife on the brink of losing her title, there's no shortage of suspects. And with rumours of a recently updated will, everyone has a motive…Solving an impossible murder is no easy feat, and for our trio, there's also the small matter of juggling their lives with the investigation.
