It has been a long time since a series of books were brought out to equal Enid Blyton’s Famous Five and Secret Seven – but here is the first instalment in Theresa Sargeant’s new children’s series “The Drainpipe Gang”.
Theresa originally invented these stories as bedtime stories for her children and for some unknown reason wrote them down. 
It is only now they are being published and the world’s children will be better off for it.
