Inspector Edmund Reid has her attack occuring 'on the pathway opposite no 10 Brick Lane'.
Most books say it was near the chocolate/mustard factory (which concurs) but many maps have it on the corner of Osborne/Brick Lane and Wentworth/Old Montague - usually the SW or NW corners.
Assuming Brick Lane didn't start numbering from no 10 at that corner, I presume it must be further north of the crossroads.
Does anyone know the numbering of the lower eastern side of Brick Lane?
