Bognor braves the frost to discover who has murdered Canada's richest man In his lavish private train car, Sir Roderick Farquhar draws a bath. When it has been filled to his satisfaction, the portly captain of industry tips in three drops of bath oil and lowers himself into the steam. Within seconds, the poison in the oil has stopped his heart and ruined Simon Bognor's winter. A special investigator for Britain's Board of Trade, Bognor makes the mistake of believing a Canadian friend's assurances that Toronto is never cold in November. He is coatless and shivering when he learns the news about Farquhar, an unsavory businessman whom the Board of Trade had previously suspected of drug smuggling, identity fraud, and worse. Sir Roderick had ties to organized crime, pro-Nazi groups, and Amtrak, and Bognor will have to determine which faction poisoned the man's bath-or shiver to death trying.
