Corre el ano de 1864. En la ribera del Tamesis Monk queda consternado ante la espantosa mutilacion de una mujer cuyo cadaver es hallado en el embarcadero de Limehouse. Pero cuando investiga el brutal asesinato y descubre la relacion de la victima con el doctor Lambourn, brillante cientifico fallecido recientemente y acerrimo defensor de una nueva ley de farmacia para regular la venta de opio, resulta evidente que no todo es lo que parece. / As commander of the River Police, Monk is accustomed to violent death, but the mutilated female body found on Limehouse Pier one chilly December morning moves him with horror and pity. Her waterfront neighbors can tell him little, only that the same unknown gentleman had visited her once a month for many years.
