El marido de Genevieve Stonefield, Angus, lleva desaparecido tres dias cuando ella decide visitar al detective Monk. La mujer esta convencida de que ha sido asesinado por Caleb, hermano gemelo de su esposo, pues la relacion entre ambos ha llegado a ser violenta. Pero Monk no esta dispuesto a admitir que se haya cometido un asesinato ni a senalar a un culpable, aunque lo cierto es que Angus parece haberse esfumado. / Perry's lingering fame from the murder she committed as an adolescent won't hurt her latest book's popularity, but there's no doubt that her historical mysteries would be critical and popular successes no matter what her background. Victorian detective William Monk returns, this time in one of the most challenging cases he's ever faced. Genevieve Stonefield begs Monk to find her missing husband, Angus, whom she fears has been killed by his twin brother, Caleb.
