A collection of the eight current titles in the Mrs Pargeter series by Simon Brett is on sale for $0.99/£0.99 at Kindle US/UK right now. This includes: A Nice Class of Corpse, Mrs, Presumed Dead, Mrs Pargeter’s Package, Mrs Pargeter’s Pound of Flesh, Mrs Pargeter’s Plot, Mrs Pargeter’s Point of Honour, Mrs Pargeter’s Principle, and Mrs Pargeter’s Public Relations.
Note: there is also a new book in this series, Mrs Pargeter’s Patio, coming in October, and I’ve literally just read an advance review copy, and loved it.
