The Amulet of Samarkand

charms to secure the disc and check for snares, but all was well. With shaking legs, he stepped from his circle.
    His first summons had been successful.
    The imprisoned imp was surly and impudent, but by applying a small spell that amounted to a brisk electric shock, Nathaniel could induce it to reveal true glimpses of things happening far away. It was able to report conversations it overheard as well as to reveal them visually in the disc. Nathaniel kept his crude but effective scrying glass hidden under the roof tiles outside the skylight, and with its aid learned many things.
    As a trial, he directed the imp to reveal what went on in his master's study. After a morning's observation, he discovered that Underwood spent most of his time on the telephone, attempting to keep abreast of political developments. He seemed to be paranoid that his enemies in Parliament were seeking his downfall. Nathaniel found this interesting in principle, but dull in the details, and soon left off spying on his master.
    Next he observed Ms. Lutyens from afar. The mist swirled across the disc, cleared, and with a quickening heart, Nathaniel glimpsed her again as he remembered her so well: smiling, working... and teaching. The disc's image shifted across to reveal a small, gap-toothed boy apprentice, drawing furiously in a sketchpad and evidently hanging on Ms. Lutyens's every word. Nathaniel's eyes burned hot with jealousy and grief. In a choked voice, he ordered the image to vanish, grinding his teeth at the laughter that bubbled up from the delighted imp.
     
    Nathaniel then turned his attention to his main objective. Late one evening, he ordered the imp to spy on Simon Lovelace, but was disconcerted to see the baby's face appear in the burnished bronze instead.
    "What are you doing?" Nathaniel cried. "I've given you the order—now obey!"
    The baby wrinkled its nose and spoke in a disconcertingly deep voice. "Trouble is, this one's tricky, innit?" it said. "He's got barriers up. Not sure I can pass 'em. Might set off a spot of bother, if you know what I mean."
    Nathaniel raised a hand and waved it menacingly. "Are you saying it's impossible?"
    The baby winced and extended a pointed tongue gingerly out of the side of its mouth, as if licking old wounds. "Not impossible, no. Just difficult."
    "Well, then."
    The baby sighed heavily and vanished. After a short pause, a flickering image began to form in the disc. It blurred and leaped like a badly tuned television. Nathaniel cursed. He was about to speak the words of the Punitive Jab when he considered that this was probably the best the imp could do. He bent close to the disc and gazed into it, focusing on the scene within....
    A man was sitting at a table, typing rapidly into a laptop computer.
    Nathaniel's eyes narrowed. It was Simon Lovelace, all right.
    The imp's vantage point was from the ceiling, and Nathaniel had a good view of the room behind the magician, although it was a little distorted, as if seen through a fish-eye lens. The room was in shadow; the only light came from a lamp on Lovelace's desk. In the background was a set of dark curtains, stretching from ceiling to floor.
    The magician typed. He wore a dinner jacket, with the tie hanging loose. Once or twice he scratched his nose.
    Suddenly the baby's face cut in.
    "Can't take much more of this," it sniffed. "I'm bored, innit, and like I say, if we stick around too long, there could be trouble."
    "You'll stick with it till I say so," Nathaniel snarled. He spoke a syllable, and the baby scrunched up its eyes with pain.
    "All right, all right! How could you do that to a wee babe, you monster!" The face flicked out and the scene reappeared. Lovelace was still seated, still typing. Nathaniel wished he could get a closer look at the papers on his desk, but magicians often had sensors on their person to detect unexpected magic in their vicinity. It would not be wise to stray too near. This was as good a view as he was going to—
    Nathaniel jumped.
    Someone else was in Simon Lovelace's room, standing in the shadows by the curtains. Nathaniel had not seen him enter; and nor, for that matter, had the magician, who was still typing away with his back to the intruder. The figure was a tall, massively built man, swathed in a long leather traveling cape that extended almost to the bottom of his boots. Both cape and boots were heavily stained with mud and wear. A thick black beard covered most of the man's face; above it, his eyes
