This is a terrific read.A compelling and complex mystery where the events of the past impact upon the present.David Audley is one of the great characters of spy fiction.He is brilliant,arrogant and fallible.An intelligence grandmaster setting out his subordinates to coax the solution to him.Here the events of the past impact upon the present.Audley's protege Paul Mitchell has to find out exactly what happened then to find the solution now.
I cannot recommend this book,and all the books in this series,too highly.
