The empty barrel, selected at random from the neatly stacked collection, seems quite ordinary. Looking into the bung and even probing with a slender weapon reveals no false bottom or other abnormality. The ale pours smoothly from the huge built in cask into the small one and it is no challenge for the burly Constables to roll it up the ramp, harness it and lift it upstairs using the rope and pulley arrangement.
The theft does not appear to occur during delivery, sale or movement upstairs. Most curious.
OOC: all present may make a hearing check.
