"Then, just when the whole wretched stew was thickening, he’d invented craniometrics. Bad coppers had always had their ways of finding out if someone was guilty. Back in the old days—hah, now—these included thumbscrews, hammers, small pointed bits of wood and, of course, the common desk drawer, always a boon to the copper in a hurry. Swing didn’t need any of this. He could tell if you were guilty by looking at your eyebrows. He measured people. He used calipers and a steel ruler. And he quietly wrote down the measurements, and did some sums, such as dividing the length of the nose by the circumference of the head and multiplying it by the width of the space between the eyes.
