I had noticed a hazy connection between the body and a man named Paul Le Roux, a South African who was reputed to be the most prolific international criminal of the 21st century. The scant information I could find on Le Roux suggested his involvement in weapons shipments, gold smuggling, and online prescription-drug sales. But he was also a kind of phantom, reportedly captured by the United States Drug Enforcement Administration in 2012 and then disappeared to work as a valuable asset. My attempts to find out who Le Roux really was, and why the U.S. wanted so badly to keep him a secret, had led me from New York to Manila and then to this vacant lot, where I suspected that Le Roux’s ghostly influence had once been manifest.
