Belgravia

The Trenchard family have recently ascended to the aristocratic society of London's Belgravia, but a decades old love affair comes back to haunt them and jeopardise the happiness of many.

Anne tells Caroline a secret which puts the women in opposition; a surprise guest at a lavish party hosted by Caroline forces James to reveal a truth that threatens to tear the Trenchards apart.

The depths of Stephen's problems are revealed, causing John to set his manipulative sights on Charles and Caroline as a way to make money; Susan isn't shy about exploiting the Trenchard's new social circle.

Caroline organises a secret outing which compromises both Anne and Lady Maria; Susan’s indulgent behaviour catches up with her.

A jealous Oliver threatens to ruin the lives of many as he makes a shocking discovery about Charles. John's plans are jeopardised, making him dangerous; he enlists the help of the Trenchard staff to stoop to new lows.

Charles receives a mysterious olive branch, but the offer of reconciliation places him in grave danger.
