First you might send for Waldo - if it's a real emergency. Actually you'd have to go to Waldo. Ill-tempered, domineering and mean-minded, he lives off-earth in his own bubble satellite, along with his faithful hound Baldur - the only guard dog to have mastered the weightlessness of space. But when it seems the fundamental laws of physics are ceasing to operate, then only Waldo, difficult though he is, has the genius to solve your problems. And then you might consider Magic, Inc. - a story of the future when the supernatural has become big business, when witchcraft is regulated by the Chamber of Commerce, and a very traditional protection racket is moving in on the neighbourhood - using some very elemental threats.
