Obviously an outdated read nowadays but it's interesting enough for those seeking an extra Sweeney fix if they've watched all the episodes in the The Sweeney T.V series many times.
I was surprised by the frosty relationship between Carter and Regan in this book. This is the only one that I've read to date in the series of books published by Futura Publications in the 1970s about Regan. Indeed, George Carter plays a very minor role in this book.
