Ghost Story (The Dresden Files 13)

learned how to do magic the hard way first—all of it in my head. Only after I’d proved I could do it without the aid of props did Justin tell me that it was even possible to use them. Over the years, I’d practiced fairly complex thaumaturgic spells without props maybe once a season, keeping my concentration and imagination sharp. It was a damned good thing I had. Working magic as a ghost was all about doing it au naturel.

I reached into my memory to produce the construct I’d need to stand in for Molly in the tracking spell. At the time, I’d been handed a lot to process, and I hadn’t really taken stock of exactly what kind of shape Molly was in. I’d seen that she was under strain, but upon closely reviewing the memory, I was somewhat shocked at how gaunt and weary she looked. Molly had always been the sort of young person who almost glowed with good health. After six months on her own, she looked like an escapee from a gulag: scrawny, tough, and beaten down, if not broken.

I added more than that to the image. I imagined her cheery goodwill, the self-loathing she still sometimes felt for the pain she’d caused her friends in the days before I agreed to teach her. I thought of her precise, orderly approach to her studies, so much different from my own, her diligence, and the occasional arrogance that pretty much every young wizard has until they’ve walked into enough walls to know better. I thought of the most powerful force in her life, a deep and abiding love for her family, and added in the desolation she must be feeling to be separated from them. Eager, beautiful, dangerous Molly.

I held that image of my apprentice in mind, drew together my will, and tapped into the recollection of one of my more memorable tracking spells, all at the same time. I established the pattern of the modified version of the spell I’d had to cobble together, walked, chewed bubble gum, and released the spell with a murmured word.

The power surged out through me, and a precise, powerful force spun me into a pirouette. I extended my left arm, index finger pointing, and felt a sharp tug against it each time it passed an easterly point of the compass. Within a couple of seconds I stopped spinning, rotated a little past the point, and then settled back slightly in the opposite direction. My index finger pointed straight at the heart of the city.

“Crombie,” I said, “eat your heart out.”

I followed the spell to Molly.

I pulled my vanishing act and went zipping downtown a few hundred yards at a time. I paused to check the spell twice more and correct my course, though by the third check, I was starting to feel like a human weather vane. I had to stop more frequently as I got closer to make sure I was moving in the right direction, and the trail took me down into the great towers within the Loop, where the buildings rose high enough to form what felt like the walls of a deep ravine, a man-made canyon of glass, steel, and stone.

I wasn’t terribly surprised when the spell led me to the lower streets. Some of the streets downtown have two or even three levels. One is up on the surface, with the others stacked below it. A lot of the buildings have upper and lower entrances and parking as well, doubling the amount of access to the buildings within those blocks.

There were also plenty of empty spaces, pseudo-alleyways, walkways, and crawl spaces. Here and there, abandoned chambers in the basements and subbasements of the buildings above sat in silent darkness, waiting to be remade into something new. The commuter tunnels could connect down there, and there were several entrances to the insane, deadly labyrinth beneath the city known as Undertown.

Chicago cops patrolled the lower streets on a regular basis. Things came slinking out of Undertown to prowl the darkness. Traffic would blaze through on the actual streets, which were occasionally only separated from the sidewalks by a stripe of faded paint.

All in all, it’s not the sort of place a sane person will casually wander through.

I found Molly standing in one of the narrow alleyways. Snow had fallen through a grate twenty feet overhead and covered the ground. She was dressed in the same rags I’d seen the night before, with her arms clenched around
