Fun, but not my favorite, although I always enjoy seeing Farrell pop up.
Carstairs has received a message from Farrell asking that Emily and Cyrus meet him in Sicily. He is searching for a possibly-authentic signature of Julius Caesar, but why he wants Emily and Cyrus is a mystery. Cyrus can’t go, but Emily is free, and Carstairs promises Cyrus that another agent will go with Emily. So after attending a funeral and taking photos of all the mourners/attendees, she is off to Palermo.
The other agent meets Emily at the airport—a young woman named Kate Rossiter. They meet Farrell, who has a baffling story to tell. First of all, he had been shot at and was just nicked on the ankle; he has been hiding out for two days and the wound has become infected. But the most astonishing thing is that Farrell swears he has seen the assassin, Aristotle, who had been on the African safari when Emily first met Cyrus. Aristotle, who had been arrested, tried, convicted and sent to prison for the rest of his life! He couldn’t possibly be in Sicily.
It is quickly apparent that bad guys are indeed in pursuit of Farrell and now Kate and Emily. Kate takes Emily and Farrell to an estate belonging to her aunt Franca. Aunt Franca turns out to be quite a mysterious character herself. But all’s well that ends well—the bad guys are caught, the assassin, Aristotle, is sent back to prison and Farrell has fallen in love.
