# Sir James Lubbock — The Documents in the Case character guide

> Sir James Lubbock in The Documents in the Case by Dorothy L. Sayers.

**Role:** supporting

**Also known as:** Jim, Jimmy, Sir James, James Lubbock, Lubbock

**First appearance:** 0003-1-agatha-milsom-to-olive-farebrother

## Snapshot

A Harrison family intimate whose well-placed presence at awkward moments makes him both useful witness and quiet complication in the case.

## Who they are

Sir James moves easily among the Harrisons, close enough to be called Jim and to be on hand when the household's private troubles spill into public inquiry. His friendship gives him access to conversations and confidences that outsiders would never hear, and his testimony carries the weight of a man who was simply there. In a story built from letters, depositions, and contradictory memories, he is one of the few figures whose account the investigators can lean on — which is precisely why his silences matter.
