From mysterfile dot com: " When Anthony Price is on form he really. does write a.very good novel of espionage and intrigue – and in this one he’s quite definitely on form. The particularly intriguing puzzle he poses is why should anyone in 1974 want to kill off those few remaining people with expert knowledge about a little known first War battle waged in 1916.

One of the intended victims is young military historian Paul Mitchell, but by sheer luck he survives,·and is at once recruited to find the reasons by Dr. David Audley, that devious agent for the Defence Ministry."
