The Sirens Sang of Murder ht-3
by Sarah Caudwell
This the third in the Hilary Tamar series, Oxford don who solves the cases brought to the professor's attention by the group of friends who work as lawyers in New Square, London. In this one, Cantrip has gone off to the Channel Islands on a tax-law case, and is indulging his love of telex machines by sending plenty back home. It's through these that Hilary and the others gain enough information to solve a mystery after a companion of Cantrips is killed.
