John George Haig smiled from the back of an English pub and sipped his murlow. The dapper 35-year-old caught the eye of a young

woman who edged toward his table to join him. Normally, Haig would have loved to chat her up, but that night he brushed her off.

He had other matters to attend to.

After she left, Haig waved over a man from the end of the bar. William Mc Swan.

William grinned and hurried over.

He clinked Higgs glass, and the two started celebrating.

Tonight, September 9, 1944, was the night William would disappear.

Haig had promised his friend he knew a place where William could lay low to avoid conscription.

Somewhere the government could never find him.

After William had drunk plenty of wine, Haig led him down to the so-called safe house, an out-of-the-way basement apartment he owned.

There, Haig kept his promise.

William McSwan did disappear, but he wasn't just in hiding. He was never coming back. Hi, I'm Greg Polson. This is Serial Killers, a parcast original. Every episode we dive
