A simple stone cellar full of boxes and crates which you would find beneath any Highstreet shop.
The Cellar stinks of death and a half eaten and mangled corpse lies in the middle of the floor. Blood and gore is splattered everywhere.
Examining the corpse reveals bite and claw marks. The victim was obviously killed by a wild animal.
Search the cellar will reveal a table with ledgers and notes on it. Reading them reveals that the shop was being used as the cover for two Dimir spies called Baldrick & Jenna Bootlick. The body must belong to one of them. The notes reveal that the spies were watching the Silver Street Casino opposite, and had orders to try and find something incriminating the Dimir could use to blackmail the owner.
There is no point checking trading licences for this business, the proprietors are dead or missing, and the business looks abandoned.
