Corrigan is at once a mordant comedy of manners and a very modern morality play. Since her husband's death, the increasingly frail Mrs. Blunt has had only her trips to his grave to look forward to. Her raucous housekeeper's conversation, and cooking, are best forgotten. Nadine, her daughter, is an infrequent, uneasy visitor. Then one day a charming, wheelchair-bound Irishman shows up at Mrs. Blunt's door in search of charitable contributions. Corrigan is an arch manipulator, Mrs. Blunt is his mark, and before long we realize that they are made for each other. As the two grow ever more entrenched, Nadine fears for her mother's safety (or is it for her own inheritance?).
With Corrigan Caroline Blackwood takes a long, hard look at our dearly beloved notions of saints and sinners, victims and villains, patrimony and present pleasure, and winks.
