The Amulet of Samarkand

insects, or eagles from amoebae. However, broadly speaking, there are five basic ranks that you are likely to find working in a magician's service. These are, in descending order of power and general awe: marids, afrits, djinn, foliots, imps. (There are legions of lowly sprites that are weaker than the imps, but magicians rarely bother summoning these. Likewise, far above the marids exist great entities of terrible power; they are seldom seen on Earth, since few magicians dare even uncover their names.) A detailed knowledge of this hierarchy is vitally important for both magicians and for us, since survival frequently depends on knowing exactly where you stand. For example, as a particularly fine specimen of a djinni, I treat other djinn and anything above my rank with a certain degree of courtesy, but give foliots and imps short shrift.
     
    I flew from Hampstead at top speed and took shelter under the eaves of a deserted house beside the Thames, where I preened my feathers and watched the sky. After a time, seven small spheres of red light passed across the heavens at low altitude. When they reached the middle of the river, they split forces: three continued south, two went west, two east. I pressed myself deep into the shadows of the roof, but couldn't help notice the Amulet giving an extra-vibrant throb as the questing spheres disappeared downriver. This unnerved me; shortly afterward I departed to a girder halfway up a crane on the opposite bank, where they were erecting a swanky riverside condo for the magical gentry.
    Five silent minutes passed. The river sucked and swirled round the muddy posts of the wharf. Clouds passed over the moon. A sudden green and sickly light flared in all the windows of the deserted house on the other side of the river. Hunched shadows moved within it, searching. They found nothing; the light congealed and became a glowing mist that drifted from the windows and was blown away. Darkness shrouded the house again. I flew south at once, darting and swooping from street to street.
    For half the night I continued my frantic, fugitive dance across London. The spheres[4] were out in even greater numbers than I had feared (evidently more than one magician had summoned them) and appeared above me at regular intervals. To keep safe I had to keep moving, and even then I was nearly caught twice. Once I flew around an office block and nearly collided with a sphere coming the other way; another came upon me as, overcome with exhaustion, I huddled in a birch tree in Green Park. On both occasions I managed to escape before reinforcements arrived.
     
    [4] Search spheres like these are a kind of sturdy imp. They possess giant scaly ears and a single bristled nostril, which make them particularly sensitive to magical pulsation and extremely irritable when exposed to any loud noise or pungent smell. For some of the night I was consequently forced to bunker down in the middle of Rotherhithe Sewage Works.
     
    Before long I was on my last wings. The constant drag of supporting my physical form was wearing me down and using up precious energy. So I decided to adopt a different plan—to find a place where the Amulet's pulse would be drowned out by other magical emissions. It was time to mingle with the many-headed multitude, the great unwashed: in other words, with people. I was that desperate.
    I flew back to the center of the city. Even at this late hour, the tourists in Trafalgar Square still flowed around the base of Nelson's Column in a gaudy tide, buying cut-price charms from the official vending booths wedged between the lions. A cacophony of magical pulses rose up from the square. It was as good a place as anywhere to hide.
     
    A bolt of feathered lightning plunged down out of the night and disappeared into the narrow space between two stalls. Presently a young, sad-eyed Egyptian boy emerged and elbowed his way into the throng. He wore new blue jeans and a padded black bomber jacket over a white T-shirt; also a pair of big white trainers with laces that were constantly coming loose. He mingled with the crowd.
    I felt the Amulet burning against my chest. At regular intervals it sent out little waves of intense heat in double bursts, like heartbeats. I fervently hoped that this signal would now be swallowed by the auras all around.
    Much of the magic here was all show, no substance. The plaza was littered with licensed quacks selling minor charms and trinkets that had been approved by the
