When Yasmin finds a jeweled egg in her grandfather s shed, her first thought is to sell it. Unfortunately, the object is no valuable Faberge antique but a dangerous weapon from another planet. Worse still, the buyer she finds online is a Russian secret agent working for the Committee for Extraterrestrial Research, who promptly swipes it, kills her brother Sayed, and lands her in hospital. When Sgt. Andy Davidson realizes that he s not dealing with an ordinary double shooting, he calls Gwen Cooper, who breaks the bad news about the egg and its deadly contents. With no Torchwood to help, and Gwen in America, it s up to Andy and Yasmin to follow the trail of the Shiva virus all the way from Cardiff to the British Museum."
