Charlie Shean now briefed the criminalist on where they needed his expertise. “We’ve searched and we’ve done the analysis. But most of the results’re just raw data. We don’t know what to make of it. If you could offer some thoughts it’d be much appreciated.”

Rhyme was taking all this in as his eyes swept the ceiling. Then abruptly: “Sachs, let’s get a chart going.”

Rhyme used graphics in running his cases—having someone write down the evidence that had been gathered—in front of which he would then wheel back and forth, frowning and muttering to himself, as deductions and conclusions came or didn’t come. Shean explained what they’d found and she wrote.
