Meg Langslow is pregnant with twins when Michael asks if she wouldn't mind having a houseguest. One of his doctoral students is directing his new translation of a play by a minor Spanish playwright, who has agreed to come to town for the production. Surely they can spare some room for such an important academic cause?
Senor Mendoza turns out to be a partygoer who loves to spend raucous evenings among adoring students...at Casa Langslow. Into this chaos arrives the dean of the English department, who insists the play be canceled. Then the unthinkable happens: the dean is found murdered, and Meg's house has become a crime scene. Now it's up to Meg to help Chief Burke solve the murders, rescue the student's dissertation, make sure Michael doesn't lose tenure, and, while she's at it, give birth to twins. Encore! Encore!
