Time enough for that another day. First he had a vital task to accomplish. From one pocket he drew a plastic bag and a half—brick found in his master's garden. From another he took the tobacco tin. Brick and tin went into the bag, the head of which he tied with a double knot.

Nathaniel gave a quick glance both ways along the bridge. Other pedestrians hurried past him, heads down, shoulders hunched. No one glanced in his direction. Without any more ado, he tossed the package over the balustrade and watched it fall.

Down… down… By the end it was nothing but a white speck. He could barely see the splash.

Gone. Sunk like a stone.

Nathaniel pulled up the collar of his jacket, shielding his neck from the wind gusting along the river. He was safe. Well, safe as he could be for the moment. He had carried out his threat. If Bartimaeus dared betray him now…

It began to rain as he made his way back along the bridge to the bus stop. He walked slowly, lost in thought, almost colliding with several hurrying commuters coming in the opposite direction. They cursed him as they passed, but he barely noticed. Safe… That was all that mattered…

A great weariness descended upon him with every step.

When I set out from the boy's attic window, my head was so full of competing plans and complex stratagems that I didn't look where I was going and flew straight into a chimney.

Something symbolic in that. It's what fake freedom does for you.

Off I went, flying through the air, one of a million pigeons in the great metropolis. The sun was on my wings, the cold air ruffled my handsome feathers. The endless rows of gray—brown roofs stretched below me and away to the dim horizon like the furrows of a giant autumn field. How that great space called to me. I wanted to fly until I had left the cursed city far behind, never looking back. I could have done so. No one would have stopped me. I would not be summoned back.

But I could not follow this desire. The boy had made quite clear what would happen if I failed to spy on Simon Lovelace and dish the dirt on him. Sure, I could go anywhere I wanted right now. Sure, I could use any methods I chose to acquire my info (bearing in mind that anything I did that harmed Nathaniel would in due course harm me too). Sure, the boy would not summon me for a while at least. (He was weary and needed rest.[42]) Sure, I had a month to do the job. But I still had to obey his orders to his satisfaction. If not, I had an appointment with Old Chokey, which at that moment was probably settling softly into the thick, dark ooze at the bottom of the Thames.

Freedom is an illusion. It always comes at a price.

Thinking things through, I decided that I had the meager choice of starting with a known place or with a known fact. The place was Simon Lovelace's villa in Hampstead, where much of his secret business presumably occurred. I did not wish to enter it again, but perhaps I could mount a watch outside and see who went in and who went out. The fact was that the magician had seemingly come into possession of the Amulet of Samarkand by ill means. Perhaps I could find someone who knew more about the object's recent history, such as who had owned it last.

Of the two starting points, visiting Hampstead seemed the best way to begin. At least I knew how to get there.

This time I kept as far away as possible. Finding a house on the opposite side of the road that afforded a decent view of the villa's front drive and gate, I alighted upon it and perched on the gutter. Then I surveyed the terrain. A few changes had been made to Lovelace's pad since the night before. The defense nexus had been repaired and strengthened with an extra layer, while the most badly scorched trees had been cut up and taken away. More ominously, several tall, thin, reddish creatures were now prowling the lawns on the fourth and fifth planes.

There was no sign of Lovelace, Faquarl, or Jabor, but then I didn't expect anything right away. I was bound to have to wait for an hour or so. Fluffing up my feathers against the wind, I settled down to my surveillance.

Three days I stayed on that gutter. Three whole days. It did me good to rest myself, I'm sure, but the ache that grew up within my manifestation made me fretful. Moreover, I was very bored. Nothing significant happened.

Each morning, an elderly gardener toddled around the estate scattering fertilizer on the stretches of lawn where Jabor's Detonations had landed. In the afternoons, he snipped at token stems and raked the drive before pottering in for a cup of tea. He was oblivious to the red things, three of which stalked him at all times, like giant yearning birds of prey. No doubt only the strict terms of their summoning prevented them from devouring him.

Each evening, a flotilla of search spheres emerged to resume their hunt across the city. The magician himself remained inside, doubtless orchestrating other attempts to locate his amulet. I wondered idly whether Faquarl and Jabor had suffered for letting me escape. One could only hope.

On the morning of the third day, a soft coo of approval broke my concentration. A small, well—presented pigeon had appeared on the guttering to my right and was looking at me with a distinctly interested tilt of the head. Something about it made me suspect it was female. I gave what I hoped was a haughty and dismissive coo and looked away. The pigeon gave a coquettish hop along the guttering. Just what I needed: an amorous bird. I edged away. She hopped a little closer. I edged away again. Now I was right at the end of the gutter, perched above the opening to the drainpipe.

It was tempting to turn into an alley cat and frighten her out of her feathers, but it was too risky to make a change so close to the villa. I was just about to fly elsewhere, when at long last I spotted something leaving Simon Lovelace's compound.

A small circular hole widened in the shimmering blue nexus and a bottle—green imp with bat's wings and the snout of a pig issued through it. The hole closed up; the imp beat his wings and flew down the road at streetlamp height.

He carried a pair of letters in one paw.

At that moment, a purring coo sounded directly in my ear. I half turned my head—and looked directly into the beak of that benighted she—pigeon. With devious feminine cunning she'd seized the opportunity to snuggle right up close.

My response was eloquent and brief. She got a wingtip in the eye and a kick in the plumage. And with that I was airborne, following the imp.

It was clear to me that he was a messenger of some kind, probably entrusted with something too dangerous or secret for telephone or mail. I had seen creatures of his kind before.[43] Whatever he was carrying now, this was my first opportunity to spy on Lovelace's doings.

The imp drifted over some gardens, soaring on an updraft. I followed, laboring somewhat on my stubby wings. As I went I considered the situation carefully. The safest and most sensible thing to do was to ignore the envelopes he was carrying and concentrate instead on making friends with him. I could, for instance, adopt the semblance of another messenger imp and start up a conversation, perhaps winning his confidence during the course of several «chance» meetings. If I were patient, friendly and casual enough, he would no doubt eventually spill some beans…

Or I could just beat him up instead. This was a quicker and more direct approach and all in all I favored it. So I followed the imp at a discreet distance and jumped him over Hampstead Heath.
