"This is the third new Willis Hall in successive years - a trilogy of Christmas Eve in the Gaolhouse jollies that started with Kidnapped at Christmas, progressed through Christmas Crackers and has now attained immaturity with A Right Caper . . .being concerned with a little Hitler of a detective, and two screws (as in prison) who have lost their thread. Our heroes are two convicts - a short fat one, and an even shorter thin one - escaping to find a Christmas tree. So much for the plot." These three plays, published jointly by Heinemann and Samuel French, guarantee a particularly merry Christmas to all who read, perform, or see them.
