On a visit to the estate of her friend, the young and beautiful Isobel Payne, Countess of Scargrave, Jane bears witness to a tragedy. Isobel's husband--a gentleman of mature years--is felled by a mysterious and agonizing ailment. The Earl's death seems a cruel blow of fate for the newly married Isobel. Yet the bereaved widow soon finds that it's only the beginning of her misfortune...as she receives a sinister missive accusing her and the Earl's nephew of adultery--and murder. Desperately afraid that the letter will expose her to the worst sort of scandal, Isobel begs Jane for help. And Jane finds herself embroiled in a perilous investigation that will soon have her following a trail of clues that leads all the way to Newgate Prison and the House of Lords--a trail that may well place Jane's own person in the gravest jeopardy.
