The Quick Red Fox is the 4th in the classic (and awesome, IMO) Travis McGee series by John D. MacDonald. It has dropped to $2.99 at Kindle and Kobo US. The titles in this series very rarely go on sale in the US – this one was last on sale about 3 1/2 years ago. They also don’t go on sale for very long, and are outrageously priced when not on sale, so grab this one now if you want it. Otherwise, you’ll have another 3 1/2 years to wait!
