Cotton Malone is a retired Magellan Billet agent trying to live a quiet life as a bookseller, but he keeps getting pulled back in. This time someone is stealing from Ludwig II's castle, Herrenchiemsee. What ensues is an engrossing tale entwining mystery, adventure, and history into a rollercoaster ride of reading delight.
Cotton is, as always, an intriguing protagonist. The surrounding characters unfold, develop, and shift in interesting ways. The underlying historical mystery is engrossing.
I definitely recommend this one. Knowing the characters and the series is helpful. I think bits may be confusing without knowing the history, but the critical bits are well filled in.
