Jonathan Maitland has already written two memorable plays for the Park Theatre. Dead Sheep – now on tour – is a very funny and shrewd look at the fatal consequences for Mrs Thatcher of underestimating Sir Geoffrey Howe. Though it took some flak, in the run-up to the premiere, for insensitivity to the victims, An Audience With Jimmy Savile proved to be a responsibly shocking and well-researched take on how and why this prolific paedophile managed to forge a unique role in English culture and got away with grooming a nation. Maitland has a keen instinct for stories that will generate passionate discussion and a knack for asking the illuminating awkward questions – as one might expect from a man who was a television reporter for thirty years before he became a dramatist.

Now, in this latest trenchant piece for the Park, he turns his attention to the topical issue of doping in sport. The title derives from what he calls "the first rule in the doper's handbook”; if you're accused of cheating, deny it; deny it again and “carry on denying it until you can’t”. A Faustian drama, the piece focuses on Eve (Juma Sharkah), a promising black athlete who has her sights set on being the fastest 100m sprinter in the world. She brushes off the misgivings of her sports journalist boyfriend Tom (Daniel Fraser) and switches to a ruthless new coach, Rona (Zoe Waites), who wastes no time in manipulatively pitting her against a rival runner (Shvorne Marks) and putting pressure on her to shed Tom.

The physician Robert Goldman discovered that more than fifty percent of the elite athletes that he canvassed answered yes when he asked them the following question: if he or she could take a totally undetectable pill that would absolutely guarantee them a gold medal, would they take it, even if they knew it would kill them within five years? Rona reports this to Eve at the start of her Mephistopheles-like pitch. There are no known side-effects, she claims, to the cutting-edge therapy that she is offering. But will Eve be prepared to collude in the manipulation of her genes – a modification that does not come under the existing code of practice and would not show up in any legal test – in order to achieve sporting supremacy?
