Lord Fredrick Ashton may not feel ready to be a father, but with a little Ashton on the way, he's sure about one thing: The wolfish curse on his family must end soon, before the child is born. Penelope willingly takes on the challenge; when Lady Constance's doctor prescribes a seaside holiday, Penelope jumps at the chance to take the three Incorrigible children to Brighton, where she hopes to persuade the old sailor Pudge to reveal what he knows about the Ashton curse.
