First appearance: vii the black sailor

As a supporting figure in The Murders in Praed Street, The Black Sailor is not background color—the story leans on what they do once the chapter opens.

Described by Wal Snyder as a big tall man with a black beard, a scar, and a woollen cap; his existence is doubted by Ludgrove and Whyland.

The Black Sailor is the shape the killer wears when moving through Praed Street's crowds and back alleys — a scarred, bearded figure whose appearances are as deliberate as they are theatrical. Behind the disguise sits a methodical mind that studies victims' habits, engineers access through a key to a rear garden door, and treats each death as an experiment in misdirection. What unsettles the early investigation is not just the violence but the patience: the Sailor is always already gone, and the police can only chase a costume.
