Meg is eight and a half months pregnant with twins when Michael asks if she wouldn’t mind another houseguest. One of his doctoral students is directing his new translation of a play by a minor Spanish playwright, and the playwright has agreed to come to town for the production. Senor Mendoza turns out to be a drinker, a smoker, and an inveterate partygoer. Before long, Meg's kitchen is filled with the smells of Spanish food and the voices of all the wilder souls in both the drama and Spanish departments. Into this chaos arrive two prune-faced administrators, the dean of the English department and a man from the college president's office, who say that the play must be canceled. When the dean is found murdered, Meg's house becomes a crime scene, and the only way to restore peace is to help Chief Burke solve the murders - while rescuing the student's dissertation and Michael’s tenure - all before dashing off to the hospital to give birth to her twins.
