There?s a tense start to next week's Holby City, as Henrik Hanssen (Guy Henry) assembles his senior staff team in the board room. ?We have a mole in our midst and it appears they will do anything to bring this hospital down,? he tells them. What he doesn?t realise is that the mole - Madge Britton (Clare Burt) - is in the room even as he speaks. As Fletch (Alex Walkinshaw), Jac (Rosie Marcel) and Max (Jo Martin) pledge to find out the mole?s identity, will Madge be exposed as the traitor?

Meanwhile, there?s a shock for Josh (Trieve Blackwood-Cambridge) when Claudia (Lottie Tolhurst), his friend from the bulimia support group, is brought to AAU critically ill and asking to see him. As Josh waits to find out whether Claudia will pull through, he has to confront his own recent behaviour and the way he?s been coping with his illness. Has he been doing as well as he?s been trying to make out?

Max has a battle on her hands when she locks horns with a doctor from another department who?s called to Keller for a consult. He has a seriously bad attitude to his patient - but is there more going on?

Amelia (Lucy Briggs-Owen) tells Eli (Davood Ghadami) she?s giving up work to concentrate on Juliet and has started telling people at the creche that she?s Juliet?s mummy. Eli is worried that she?s moving too fast and Nicky (Belinda Owusu) could still change her mind. Then Amelia shocks him with an announcement.

Russ (Simon Slater)?s pregnant daughter Billie (Delainey Hughes) comes to the hospital in a lot of pain. She admits to Henrik that she still hasn?t told her dad about her pregnancy. Maybe it?s time for both Billie and Henrik to open up to Russ about the secrets they?ve been keeping?

And as news reaches Jac that more information has been fed to Regina Marriott about the hospital, it must mean that the mole is someone who is at work that day - which does narrow things down a bit. Has Madge made a fatal error?
