Hi Joyce,
I have seen this book for sale at
www.amazon.co.uk, although it might be out of print. I visited a brilliant Essex bookshop called Swan Libraries at the weekend, and I know that they also have stocked this series although I don't know about High Easter itself. (

I have a book called High Easter Through the 20th Century by Derek E Bircher. I bought this at the Essex Record Office. This was published by High Easter Parish Council in 2000.
