Per an email I received this morning from Joffe Books,
Sixpenny Holding, by Margaret Scutt, is being offered for free for an unspecified "limited time". I haven't read anything by this author, but do enjoy several other authors published by Joffe, including Simon Brett, Veronica Black, Nicholas Rhea, and Jeanne M Dams.
