This is one of those hidden gems that I wouldn't have normally thought to see if it hadn't been for a very special deal on the tickets (£10 tickets still available for previews including press night next week, snap 'em up I say).

It's set in rural Ireland, in a stone cottage, where put-upon 40-year old spinster Maureen (Susan Lynch) is caring for her needy and manipulative mother Mag (Rosaleen Linehan).

"I can't see how a urine infection prevents you pouring a cup of Complan or tidying up the house a bit when I'm away. It wouldn't kill you."

Maureen would love to escape, indeed she dreams of escaping and an invite to a party and subsequent romantic liaison with Pato Dooley (David Ganly) gives her a glimmer of hope.

But who will stir the lumps out of Mag's Complan?

The Young Vic has done a great job with the staging almost encasing the audience in the frequently rain-soaked cottage so that you feel holed-up with mother and daughter.

That, combined with a script that ripples with wit and pin-sharp performances (Linehan proves a master of comedy with a perfectly-timed raise of the eyebrow) quite simply had the audience hooked.

It's been a long time since I've seen a play where the audience has been so engaged the reaction has been quite so palpable: Sharp intakes of breath, muttering under breath as events twisted and turned - and so much spontaneous applause.
