I've just bought both the books recommended here 😆
The Midsomer Murder one for my Mum as she will love it and then pass on to my Dad!
And the Armchair General one for my 16yo son...he's a reluctant reader but I always buy him a book for Christmas anyway and always try to find something he might be willing to pick up! He loves history, especially the world wars, so keeping my fingers crossed this may be a winner!
