H.H. Holmes
A number a newspaper paid for.

- Confessed to twenty-seven murders in an account he was paid for and later recanted. Documented victims number roughly nine; popular accounts run as high as two hundred.
A paid confession, resold as architecture.
He is famous because a magazine bought the number. That makes him less a murderer in the record than an early proof that this market pays for arithmetic.
The staircase to nothing is the honest device: the architecture in the legend is largely the legend's own invention, and it is still what gets printed.
Nine, twenty-seven, two hundred — pick the figure that sells and the trade will run it. It ran the biggest one for a century.
