Extract from The Runaway Children, when the Hadwins, Laurel and Roots take to the water on a souped up narrow boat!
"Quick!" cried Jo "Switch on the engine!" Miles ran to the back of the barge and slipped the key into the lock. As soon as he turned it, the barge set off at an amazingly spanking pace for such a heavy vessel. Roots had just untied the rope from its mooring and was now trotting alongside with it on the towpath.
"Hey! That's them!" bawled one of the trench coats and started running towards the Judith Rose.
"They've seen us!" Roots yelled. "Press the Booster, Miles!" He was just about to hop on board as Miles touched the large red button. This caused the barge to lunge forward at such an incredible speed, it yanked the unfortunate Roots off the towpath. "Sack this!!" he hollered, clinging desperately to the rope, his feet wafting in the air behind him. "Sack this for a Kleenex full of bogies!"
"Supersonic!" whooped Miles and he waved his fist above his head as the barge blazed along the canal, sending ducks and fishermen diving for cover. "Wit woos!"
Meanwhile, Roots had recovered his balance sufficiently to press his heels into the water and lean backwards like a skier. "Look at me!" he cried, jubilantly. "I've joined the jet set!"
