This is the second appearance of that spinster schoolteacher in a somewhat collapsible story which Miss Seeton alone sustains. She's once again solicited by the Yard since she draws illumining pictures from which conclusions may otherwise be drawn--this time re some thefts and a strangler. She's also as indestructible as the ferrule on her everpresent umbrella and obviously one of those ageless oldsters to whom only Margaret Rutherford could do justice.
