I had been under the impression that the 'Five Find-Outers' series was out of print and unavailable. A listener had texted (?) in to say they were available. So, while at work this morning I did a bit of research and this is my result. Yes, indeed the 'Five Find-Outers' are aavailable, but they are only referred to as the 'Mystery' series.
Also, the 'Famous Five' series have gone into reprint, and the first 10 of them are out now with their new covers. The others are being published at the rate of about 2 per month until all 21 have been reissued.
Okay, I'll stop now with the Enid Blyton talk. Promise.
