Mummer's Close was a street in Summersea. It was situated in the Mire and ran parallel to Spice Walk, leading away from Nosegay Strut. In the morning of the 6th day of Sap Moon two derelicts sleeping on Mummer's Close had been found with the blue pox and brought to Urda's House. So far the street has only been mentioned in passing by Dedicate Crane in Briar's Book.
