History Mysteries Challenge

I recently signed up for the Historical Mysteries Challenge sponsored by Mysteries and Musings blog. The idea is to read 5 historical mysteries over the next three months. The only problem is which historical mysteries? There are so many and I'm such a huge fan that it's been hard for me to narrow it down. I do know that I don't want them to be all series mysteries. I'd like to have at least 2 that are one offs.  Here are my choices thus far.

• Tears of Pearl by Tasha Alexander
• Castle Noir by Carole Nelson Douglas
• Royal Flush by Rhys Bowen
• The Secret Adversary by Agatha Christie
• Miss Match by Sara Mills
• The Ruby in the Smoke by Philip Pullman
• The Dante Club by Matthew Pearl
• 85 Bond Street by Ellen Horan
• The Face of Stranger by Anne Perry
• Murder on Bank Street by Victoria Thompson
• The Agency: The Spy in the House - Ying Lee
• Descent into Dust - Jacqueline Lepore
• The Spymaster Chronicles - C.W. Gortner

And that's just to name a few.
