Most of the titles in the Simon Puttock/Sir Baldwin Furnshill (Knights Templar) series by Michael Jecks have dropped to between £0.99 and £2.99 each at Kindle UK. They are mostly £1.99, with several at £0.99 and a couple at £2.99. I have fond memories of picking up the early titles in this series in paperback (before e-books) while in the UK on business trips, and then reading them on the plane on the way home. The “master” link below picks them up (including a few strays), except for the 23rd book, Dispensation of Death, which seems to need its own link (???).
