Motion sensor camera

Motion sensor cameras like this one snap a brightly lit photo of whatever trips the invisible laser beam it projects. Unfortunately, it had the night off during the vigil I joined at the Tally Ho tavern.

This unit is set to look up the stairs toward the pub's upper living quarters, where the ghost of Emily--supposedly an ill-fated young lady who died under suspicious circumstances on the property during its days as a brothel and boarding house--is said to reside.
