Joe is offered the opportunity of a lifetime - but finds himself unexpectedly torn. Betsey's mother comes for a surprise stay.

Lady Hamilton is in the mood for adventure. As the Halcyon hosts a society wedding, Emma must step up to oversee it - but there is trouble brewing in the air.

Dawn, and smoke rises from another bombed out night in London. Emma washes out the insides of a Women's Voluntary Service van with her fellow member, Evelyn. Tough, working class Evelyn remarks that in the weeks that Emma's been volunteering, she's really proved her grit. Pleased, exhausted and covered in soot, she returns to begin work all over again at the Halcyon.
