"Sure thing," I said, thinking, Great… now that Jonah knows we're an item, the entire STPD will be informed by midday tomorrow. Men are worse gossips than women when it comes right down to it.

I crawled into bed at midnight and found myself tossing and turning, possibly because of the lengthy nap I'd taken in the afternoon. I don't remember the moment when I sank into a leaden sleep, but vaguely, I became aware of a pounding on my door. I opened my eyes and checked the clock. 8:02. Who the heck was it? Oh, shit. Reba was down there.

I pushed the covers back and swung my feet out on the floor, yelling, "Just a minute!"… like she could actually hear me. I dry-washed my face, pressing my fingers into my eyes until light sparks appeared on the inside of my lids. I went downstairs and let her in, saying, "Sorry, sorry, sorry. I overslept. I'll be with you in a sec."

I left her to make herself at home while I went upstairs, though in the interest of good manners, I leaned over the loft rail and called down to her. "You can put on a pot of coffee if you can figure out how."

"Don't worry about it. We can stop off at McDonald's."

"You got a deal."

I did an abbreviated bathroom tour and then pulled on jeans, a T-shirt, and tennis shoes. I retrieved my wallet and car keys from the brown-paper bag and in six minutes flat, I was ready to go out the door.

We ordered from the take-out window and then sat in the parking lot with two enormous coffees and four Egg McMuffins with extra packets of salt. Like me, Reba ate like she was competing for the land speed record. "They don't call this fast food for nuttin'," she remarked, her mouth full. There were a scant few minutes when we sank into quiet, focused on our food.

Having finished, we bundled up our trash and shoved it in the bag, which Reba pitched into the container on the sidewalk nearby. She said, "Two points. Hot damn."

While I sipped my coffee, she reached over to the rear seat and picked up three rolled cylinders of architectural plans, bound with a rubber band. She slipped the band on her wrist for safekeeping, then unfurled the first oversize sheet, which she spread across the dashboard. The paper itself was a whitish blue, with the two-dimensional rooms laid out in blue ink. The legend along the bottom read: THE BECKWITH BUILDING, 3-25-81.

Reba said, "These are the old blue-line drawings. I'm hoping they'll tell us what Beck's hiding and where he's hiding it."

"Where'd you get these?"

"We had multiples at the office – everything from framing plans to plumbing plans, heating and air conditioning, fixture requirements, you name it. Every time the architect made changes, he'd print out a new set of drawings for all the principals. Beck told me to toss 'em."

"And you had the foresight to hang on to them? I'm impressed."

"I wouldn't call it foresight. I just love the information. It's like looking at X-rays – all those cracks and bone spurs where you least expect them. Here, take a look at these and we'll compare notes. I realized last night we were going about this all wrong."

She passed me the second batch of drawings on sheets of paper that must have measured eighteen inches by twenty-four. I wrestled the first sheet into a reasonably flat position and studied the particulars. As nearly as I could tell, this had something to do with the service entrance and electrical rooms, showing the location of the meter, the transformer vault, the switchgear, electrical closets, and individual circuits. The wiring diagrams were made up of circles and wavy lines, showing the relationship of outlets to controls.

The next sheet was more interesting. It looked like a cutaway of one corner of the building from the rooftop down. According to the legend at the bottom of the page, every eighth of an inch represented one linear foot. The architect had labeled every aspect of the drawing in that freehand block lettering students must be taught the very first day at architectural school. Reba glanced over, saying, "What they're using there for stablization is a rigid core that runs down the center of the building – a structural tower that contains the restrooms, stairs, and elevators. I remember them talking about diagonal bracing and shear panels, whatever that means."

I could see the concrete columns, the location of precast concrete spandrel panels, the slab on grade and concrete pile foundation, which was backed up by a steel-stud and drywall assembly. I was hoping to spot the correlation between the lines on the page and the spaces I'd seen. The detailed drawing of the rooftop, for instance, did show the mechanicals of the elevator equipment in roughly the same position as the fakey-looking gardener's cottage. Reba put a finger on the page. "I don't like it. That other drawing shows the elevators on the far side, not this. So which is it?"
