Someone's lighting fires in old barns round Tackleford and an odd troll has been spotted living under the bridge. New chap Colm is convinced one is responsible for the other and wants Sonny and Linton to help apprehend the villain! But Lottie and Mildred have made friends with the troll and want to help find him a lady friend! A first date goes disastrously wrong and Tackleford erupts into riots and the fire brigade go mad altogether! YES BAD MACHINERY IS THE BEST OF THAT THERE IS NO DOUBT! Great story, great art, great characters, a laugh from start to finish.
