Zapped

It's the Super Solstice, Brian's last chance to get home. He just needs to break into the Protector's mysterious Henge while Howell performs the incantation to cross worlds. There's only one problem - keeping Howell alive and sober enough to cast the spell. Drastic measures are required and Howell is forced to go cold turkey - with unexpected consequences. Meanwhile Steg gets stuck into a new job, Barbara meets a tall dark stranger and Herman wonders if it's time to sell up and move to the seaside.
