The first of this series caught my eye when it was a Kindle Daily Deal last week from publisher Open Road. Today I noticed that all Brian Freemantle's backlist books were priced at $2.69 at
Kobo (discountable with coupons also), and $2.99 at
Nook,
Sony and the iTunes store. They are still priced at $7.99 at Amazon and Google Play, but this appears to be a publisher promo so those will probably drop as well. His Charlie Muffin spy series comes highly recommended by a few people on the forum, so I thought I'd post.
