In the middle of Cork, in the middle of the day, a fire blazes in a
local dance studio. Thirteen women, all promising stars of Irish folk,
die in the flames. Their young lives cut short by a tragic accident. But
where others see tragedy, DCI Katie Maguire sees murder. This is not the
first fire to sweep through Cork. And in one previous case, the victims
were dead before the fire was started. As Katie Maguire investigates the
strange, obsessive world of competitive Irish folk dancing, she must
face her most chilling killer yet.
