I've just finished reading The Famous Five Five Go To Mystery Moor on my Kindle FireHD, and I've really enjoyed it.
(Synopsis)
The Famous Five are holidaying at a Riding School, when a group of gypsies traveling by turn up with an injured horse. Talking to Sniffer, the boy whose horse has a bad leg, They hear the gypsies seem in a hurry to leave, and when the five follow, they are told to "clear off and leave us alone."
