A celebration at a turn-of-the-century manor takes a deadly twist, and everyone becomes a suspect. Twin brothers Easton and Weston are both in love with their childhood best friend Eloise. But headstrong Eloise prefers the younger brother, Wes, which is why she is heartbroken when, unexpectedly, Wes proposes to an heiress, and Eloise finds herself engaged to Easton--the twin she cannot stand. Then, during a week of celebration, Wes is poisoned. Murmurs of nightshade slip through the manor, and everyone seems to have a motive. Was it Della Drewitt--the heiress reluctant to marry Wes? Or did Easton decide killing his brother was the only way to secure Eloise's affections? Or was it the housemaid Violet, Wes's previous lover? As guests turn into suspects, attempts to kill Wes become more relentless than the storms churning the estate--who wants him dead, and why?
