The Dorset House affair

the long version

Dorset House is the home of the Claygate family, and a place where diplomats love to congregate. When young Maurice Claygate and Sophie Lenart, a notorious woman spy, are found shot dead, Inspector Arnold Box, investigating the murders, hears from Colonel Kershaw, Head of Secret Intelligence, that there are international ramifications to the case. Together the two men pursue a ruthless thief and a stolen document across France, bringing the affair to a devastating and unexpected climax in the great palace of Louis XIV, the Sun King, at Versailles. Set in late Victorian times, this is the seventh book in the "Inspector Box" series.
