Rattling the Railings

For fifteen years Alec and Brenda have looked after Alec's lively but somewhat trying Dad

Now, however, Alec's sister Pauline has left her fifth-floor flat for a bungalow, and is no longer encumbered with a husband, and Brenda feels it is high time that she, Pauline, undertook her share of Dad's care

Pauline declares that she has no intention of giving up her various plans to do this; but when Dad is brought to stay with her while Alec and Brenda go on holiday it appears she may be having a change of attitude.
