What do an Internet scam, a conference for mystery writers, and "The Great Sausage Scandal" have in common? They're all connected to the latest adventure of Addy Zhuang- an employee of the real-life bank at 221B Baker Street tasked with answering all of the mail that mystery fans send to Sherlock Holmes. In the sequel to Sherlock's Secretary, Addy, his true-crime reporter girlfriend Zabel, and his friends Sanna and Jasper travel to Scotland in order to solve a missing persons case connected to a prop from the classic movie The Private Life of Sherlock Holmes. Pretty soon, Addy and his colleagues are embroiled in a murder mystery, and the main suspect is a nobleman obsessed with one goal: hunting the Loch Ness Monster!
