A realistic statue of a naked woman is discovered in the park drawing scandalized on-lookers until one takes matters into his own hands. The discovery that it's a murder, leads Murdoch and Julia on the trail of what may be a sequential killer.
Murdoch is summoned by no less than Prime Minister Laurier to head off the launch of an explosive-armed missile set to be fired from Canada to New York City unless a ransom demand of $4 million is met within the next 24 hours.
When the lone holdout on the city council against a contentious fight to enact prohibition dies after a night in the cells of Station House 4, Murdoch and company investigate, even as the Brackenreid home hosts the prohibition movement's principal protagonist, Carrie Nation.
After a nearly 30-year interval, Murdoch is reacquainted with a fellow scholarship camper, a woman now working with a private investigator, who assists Murdoch in a present-day murder case linked to seven campmates apparently being targeted by the perpetrator of a murder at the camp in 1875.
Mr. Frank Parker, a white man, who was visiting an all black church for Sunday's service, was found dead by Miss James, Dr. Ogden's protégé. The new Chief Constable seems to be in a hurry to charge a black paritioner even before the crime has been investigated by Murdoch.
