English prof Neil Kelly, who solved the murder of his young fiancÉe Pril Lacey in the recent, mildly diverting By Frequent Anguish, now solves the murder of Pril's father Morgan--in a less arch but also less entertaining sequel. As Kelly learns from a CIA agent, Morgan has been killed out in New Mexico by a booby-trapped jack-in-the-box gift, and wife Barbara (a CIA agent) has been near-fatally injured. So Kelly reluctantly turns sleuth after a hospital visit with Barbara, heading out to visit Barbara's family in New Mexico: daughter Linn; radical son Tim; sister Em; and brother-in-law Doan, who's heavily involved in government contracts for computers and missiles. CIA and FBI types lurk on all sides; both Tim and Linn's Irish fiancÉ are suspected of possible terrorist links; another murder occurs; there are murmurings about Qadaffi and Israel. And after far too much talk (lots about Jung and Yeats), the not-very-surprising traitor/villain is unmasked. Without the charming academia atmosphere that rescued By Frequent Anguish: a literate but tedious and implausible tangle.
