#year 1889

People are dying in the streets of Whitechapel and it seems that cholera has returned caused by a contaminated water pump. Jackson,however,examining the first victim,a man who has come from the city of London,detects the cause of death as ergotism,which sends its victims mad before they perish,and which has been deliberately added to the flour at Flora Gable's mill by a self-imposed judge of morals,who is also seeking notoriety in excess of the Ripper. With Reid's wife among the stricken the Whitechapel force must combine with Inspector Ressler from the city to catch the killer.
