Mrs. Piggott is the owner of the urban apartment block 24 Flyaway Road and is the landlady of Professor Hector Alembick.
History
She is first encountered by Tintin when he goes to Alembick's address to return Alembick's briefcase, which had been left in a nearby park. It is led to believe that she was completely unaware of Alembick's kidnapping and replacement by his twin brother Alfred.
