4 Stars. These Parker Pyne stories can be confusing. They are fictional as created by Agatha Christie. The characters and the plot are fiction, but some locations and actions are real. The city clerk is Mr. Roberts, Mr. Parker Pyne's client, he's fictional, taking the sleeper train from Boulogne to Geneva. Real train, real cities. Roberts comes to Pyne because he's unhappy with his life. He needs a little excitement. He's a clerk in a large firm. As an aside, the words city clerk in Canada today means the head clerk for a large municipal government - not the meaning here. Pyne decides that a short adventure as a spy will be perfect for Roberts, and arranges with Lucas Bonnington, an actual spy but fictional, for a secret package to be carried to Geneva. Accomplished with little fanfare, Roberts is then asked to take a sleeper to Paris. Things heat up. He meets a glamorous foreigner who uses the right passwords. She is pursued by a Russian named Vassilievitch with murder on his mind. Is this a Pyne fiction within a Christie fiction? Whatever, it's delightful. If you can fathom exactly what fits where, you are better than me! Enjoy. (Jul2021/No2025)
