But one thing was bothering him. This room did not match Fredda Leving’s character. He knew her slightly, from the process of ordering Donald, and this place did not fit her. It had the feel of a male domain, somehow. Tiny details he had seen but not noted suddenly registered in Alvar’s consciousness. The size and cut of a lab coat hanging by the door, the size of the dust-sealed lab shoes sitting on the floor beneath the lab coat, certain tools stored on wall hooks that would be well out of reach for the average-sized woman.

And there was, indefinably, something about the neatness of this room that spoke of a shy, compulsive, tidyman, something that did not match an assertive woman like Fredda Leving. If she lived up to her very public image,her lab would be a mess, even after the robots got through cleaning, for she would flatly refuse to let them near most of it. The great and famous Fredda Leving, hero of robotics research, the crown jewel of science in Inferno, was not a compulsive fussbudget-but the occupant of this room clearly was.

Alvar Kresh stepped back into the hallway and checked the nameplate next to the door.Gubber Anshaw, Design and Testing Chief; it read. Well, that solved one minor mystery and replaced it with another. It wasn’t Leving’s lab, but Anshaw’s, whoever he was.

But what was Fredda Leving doing in Anshaw‘s lab, presumably alone with her assailant, in the middle of the night?

Kresh went back into the lab and walked around the rest of the room, careful not to touch anything, determined to resist the urge to go and look at the spot where the body fell. The room was a perfect forest of potential clues, jam-packed with gadgets and hardware that might have some bearing on the case, if only Alvar knew enough about experimental robotics. Was there indeed something missing, some object as big as an experimental robot, or as tiny as an advanced microcircuit, whose theft might provide a motive for this attack?

But what was the nature of the attack? He knew nothing so far.

At last, quite reluctantly, after working the rest of the crime scene and coming up with very little for his efforts, Alvar moved toward the center of the room, the center of the case, the scene of the attack.

There it was, on the floor, between the two worktables, a meter or so in front of the large robot service rack. A pool of blood, a blotchy, irregular shape about a meter across. The body as found was indicated in a glowing yellow outline that followed the contours of the body perfectly, down to the sprawled-out fingers of the left hand. The fingers seemed to be reaching toward the door, reaching for help that did not come.

Some errant part of Kresh’ s mind found itself wondering how they did that, how they put down that perfect outline. Robots in the Sheriff’s office knew how, but he did not.

But no. It was tempting to distract himself with side issues, but he could not permit himself the luxury. He knelt down and looked at what he had come to see. He had forced himself not to notice the smell of drying blood until this moment, but now he had to pay attention, and the heavy, acrid, rotting odor seemed to surge into his lungs. A wave of nausea swept over him. He ignored the stench and went on with his grim task.

The pool of blood was much smeared and splashed about by the med-robots, their footprints and other marks badly obscuring the story the floor had to tell. But that was all right. Donald would have images of the floor recorded straight off the med-robots’ eyes, what they saw the moment they came in. Computer tricks could erase all traces of the med-robots from whatever images the police observer/forensic robots had made, reconstruct the scene exactly as it was before. Some of his deputies only worked off such reconstructions, but Kresh preferred to work in the muddled-up, dirtied-up confused mess of the real-world crime scene.

The blood had virtually all clotted or dried by now. Kresh pulled a stylus from his pocket and tested the surface. Almost completely solidified. It always amazed him how fast it happened. He looked up and from the pool of blood, noted the pattern of a med-robot’s foot and then noted something else he had seen before but merely filed away until he had seen the whole room. Two other sets of prints, clearly from robotic feet, but wholly different from the med-robot’s treads. One set of prints led out the front interior into the hallway, the other out the front exterior door to the outside of the building.

And the two sets of prints might be different from the med-robot’s, but they were utterly identical to each other.

Twosets of mystery prints, exactly like each other.

“That’s what’s bothering you, isn’t it, Donald?” Alvar said, standing back up.

“What is, sir?”

“The robot footprints. The ones that make it clear that a robot-two robots-walked through the pool of blood and left Fredda Leving, quite possibly to die.”,
