Bendor and Emma investigate two paintings from Brighton's lavish Royal Pavilion - a penitent Mary Magdalene, possibly by Francesco Trevisani, and African king Balthazar, one of the three magi from the Bible, possibly by Joos van Cleve.
Bendor Grosvenor and Emma Dabiri travel to the grand Georgian mansion of Tatton Park in Cheshire, where Bendor has spotted a mysterious portrait of a 16th-century Italian physician in its collection.
Technical difficulties frustrate Bendor's attempt to uncover who painted an unfinished portrait in a Glasgow museum. Emma reveals the true identity of the sitter after 300 years.
