Louisa throws herself into running her boarding house, but mysterious guest Lazaros Vangelatos places the villa under police scrutiny.

Louisa finds herself fending off unexpected romantic advances. Leslie's arranged hunt for new guest, Colonel Ribbindane, doesn't quite go to plan when his past revisits him.

With the house guests getting ever more rowdy, Louisa worries about the villa's reputation. Spiros's increasing presence at the villa continues to delight Louisa.

Louisa's plan for a family picnic to Kalami goes awry when she inadvertently invites Spiros's wife. The Durrells are surprised to discover Captain Creech's new business venture.

With storm clouds gathering, the island realises it can no longer ignore the rumblings of war just as it looks as though the Durrells may have found their happy ending.

The King of Greece is to visit Corfu and the Durrells are keen to be part of the welcoming committee. Meanwhile, things between Spiros and Louisa get cosy.
