Louisa tries to raise some money by selling homemade food, which attracts the attention of another Englishman. However, a former lover threatens the family's idyllic existence. Gerry comes up with a plan to breed otters, Leslie accidentally shoots Roger, and Margo considers becoming a nun.
Louisa plots to expand her business selling traditional English food, ploughing all her emergency funds into the project and setting her children to work. Sven provides them with some goats, but is bemused by the prospect of spotted dick and toad in the hole, while Spiro offers some advice on how to sell things at market. Leslie embarks on a beekeeping project, but ends up getting badly stung.
Louisa struggles to adapt to Larry moving out. The thought of all her children leaving her drives her to set aside her doubts about pursuing a relationship with Hugh, which leads to a revealing conversation about Vasilia. The younger Durrell children are not sure when their mother's birthday is - so plan a party anyway.
Larry moves back into the family's villa having come down with mumps, which Louisa hopes will give Aunt Hermione an incentive to cancel her planned visit. Her hopes prove in vain when her overbearing relative turns up, accompanied by medium Mrs Haddock (Una Stubbs), who claims to be able to contact Louisa's husband. She tells Louisa that he is terribly unhappy about her numerous male admirers, fuelling her doubts over her relationship with Hugh, and proposes a seance on a stormy night to set his troubled spirit at rest.
Hugh organises a cricket match between Greek and English teams to bring everyone together. Countess Mavrodaki offers to umpire - but warns Margo that contests between the two nations are never friendly. Spiro advises Louisa that she has terrible taste in men, while Larry finds that Vasilia wants their relationship to progress faster than expected.
The family's maid goes into labour, so Leslie sends Larry to fetch Dr Petrides. However, he finds the doctor occupied, as he is in the middle of delivering his own wife's baby. Hugh has a proposition for a startled Leonora, which she promises to think about - but an altercation with Vasilia nearly ends in tragedy for them both. Donald attacks a rival suitor for Margo - who finds herself quite delighted by the thought of two men fighting over her - while Theo and Gerry make a discovery at the otters' den.
