Query: I found this book unreadable

I read a few decent reviews of this book but I found the book unreadable and tossed it. If you have not read Len Deighton and John LeCarre you should read these authors and forget about McCarry Granted the earlier Deighton in the Bernard Samson Series can be dense and heavy reading but always high on the worth it scale.
