How To Be A Jewish Detective's Mother. Bringing chicken soup to detective son Bernard, Rose Birnbaum answers the phone in his absence--he's looking for a missing boy--and is pressed into the search for a missing clown. That the two are connected you might guess from the synopsis but not from the story, which mostly involves Inspector Rose barging into the circus acts and acting like a scold. In fact you've forgotten all about Bernard by the time he turns up on the trail of the boy (just after the clown has found Inspector Rose stuck in a phone booth) who is the apprentice clown pretending to be a midget. But Mother Rose knows. . . and mothers generally will find this mishegoss funnier than kids will.
