THROUGH THE WALL

A case for the omniscient Miss Silver -- although she enters it from a far perimeter. Marian Brand, unsuspecting heiress, finds a household full of jealous family when her uncle dies and leaves her in complete power; Miss Silver, against her own best wishes, cannot get out of the blackmail case that a young singer offers her. When Marian's problems link into the murders that result from the killing of the singer -- Miss Silver shines -perhaps refulgently but always logically. Meat -- in the Britannia rules class.
