A pitch-black comic novel about Pat McNab, a middle-aged mammy’s boy in a tiny Irish village, who starts poisoning people with “emerald germs” (his homemade concoctions). As the bodies pile up, Pat descends into a fever dream of drink, memories, and murder ballads, and conversations with his dead mother. Hilarious, grotesque, and utterly unhinged – not a children’s book at all, but one of the darkest, funniest Irish novels ever written.
