Detective Superintendent Jack Hawksworth is seconded by counter-terrorism to investigate a spate of domestic events. First it was needles in strawberries, then tempering with lipstick samplers and baby formula. But when toxic mushrooms enter the market system and a death occurs, a wave of terror is set to sweep the country. Breaking news of a possible serial killer only heightens the alarm.
There are no clues, no DNA, no witnesses, no CCTV footage. Jack and his Operation Cedar must work on instinct to figure out why someone would want to harm innocent victims, each of them curiously linked to a single blood transfusion.
When a hospital bomb threat erupts, the clock is ticking, and no one is safe from the possibility of a tragedy on a catastrophic scale.
