Sackville Street — following the property trail

In Chapter 20, Jonathan visits the estate agents Mitchell, Sons & Candy in Sackville Street to discover who bought the Piccadilly mansion.

The clerk refuses to name the buyer to Jonathan. Invoking Lord Godalming changes the conversation: a letter to the aristocrat will secure the information. Pause to consider how status, paperwork and business etiquette help the hunters.

The novel names the street but gives no office number. This is a street-level literary stop, not an identification of an existing estate agency.
