Maxwell's reunion - M. J. Trow

When Peter Maxwell attends a school reunion of the class of '65, all is not as it seems among his old chums. They are career men, family men - but the years have taken their toll, and the seething tensions of the school years surface in unlikely ways. At the end of the reunion weekend, a man is dead, hanging from the bell rope of the old school. When a second death occurs, Maxwell finds himself in the midst of a murder investigation. What is the secret that has been lurking under Maxwell's nose all these years - and could he be on the murderer's list for killing No. 3?
