Because the old mass market paperbacks of the Lacey series are now very hard to find (and going for ridiculous prices on used book sites--$25; $45 and more), we are working to get the entire series republished in print (POD).
The books will be available in what's called "Expanded Distribution" which means that, while bookstores won't necessarily keep them in stock, they can special order for you (they'll be available via Ingrams). Therefore, if you don't want to order via Amazon, you will be able to find these books via Barnes & Noble and independent booksellers.
I encourage you to utilize mystery booksellers, such as Poisoned Pen (http://poisonedpen.com/) and the like, to shop for mysteries. I truly want to see these bookstores stay in business! It's wonderful to enter a bookstore where the staff knows so much about the genre and can find and recommend books at the drop of a hat. Many mystery bookstores do mail order (and online ordering), if you don't have an indie mystery bookseller near you.
I have already put the print copies of Hanover Square Affair; The Necklace Affair and other Stories; and A Death in Norfolk into expanded distribution. (It might take a few weeks before they appear as available.)
In the next weeks to months, A Regimental Murder; The Glass House; Sudbury School Murders; Body in Berkeley Square; and A Covent Garden Mystery will follow. All need to be formatted, checked, and then printed--it takes a couple weeks for them to appear for sale on Amazon after they're uploaded, and then another month or so to be available in larger distribution. I'll update the website with links as they appear.
Disappearance in Drury Lane will appear in print (and orderable by bookstores) very soon after the e-version goes online.
(And I'm writing on Drury Lane every day, don't worry).
