Watch out in Northwood public park for a group of noisy ghost-children whose excited screams are heard at dusk as they play and swing on the branches of the gnarled old trees. A grinning phantom pirate called Henry also haunts the cellars of Northwood House. Wearing black sea boots, a striped jersey, knotted scarf and single earring, he still walks the stone tunnels leading from the cellars to Castle Hill, where illicit brandy, tobacco and wines were once brought ashore by Henry and his fellow smugglers.
