**Role:** supporting

**Also known as:** MacDonald, Dear Inspector Macdonald, Mr. Mac, Mac, Alec MacDonald, Mr. MacDonald, Friend MacDonald

**First appearance:** 0001-i-the-warning

## Snapshot

The Scotland Yard man on the Birlstone case, dogged and honest, who finds himself outmaneuvered by a colleague who will not show his hand.

## Who they are

MacDonald works the murder methodically, sorting telegrams and chasing the elusive cyclist across half of England, only to be told flatly to abandon the case. He respects Holmes but resents being kept in the dark, and his blunt question about whether Mrs. Douglas and Barker are conspiring to conceal the truth pushes the inquiry toward its real shape. His sturdy professional pride makes him both a foil and a genuine partner in the investigation.
