I'm reading a thriller set in Philadelphia...it's quite good...not exactly rocket science, but ideal for evening reading. Still haven't finished The Goldfinch...really making that last!
Anyway...the present thriller involves a group of hardened cops hunting down a serial killer...and some of the victims have turned up in a disused Potters Field...well, you've never heard such a fuss and performance from these tough guys about the ghosts and how being there gives them the heebie-jeebies and a couple don't care and swagger about while their mates are crossing themselves and muttering the Hail Mary or the Lord's Prayer depending on which side of the fence they're on...
However can a burial ground of any description possibly be scary...everybody is dead. No-one is lurking just beneath the surface to shoot out a skinny hand and grab your ankle as you walk past...there isn't anybody lying in their coffin, hands neatly folded on their chest, with one eye open, so they can see a small plump child pulling the petals off their flowers and plot revenge for the next time said child comes to visit Granny.

The only person you might catch a glimpse of as they lurk behind a tombstone is probably the local 'flasher' in his customary grubby raincoat...
I suppose you might meet a necrophilic actually...but you'd have to be really unlucky and my limited experience on the subject tells me it'd be best if you just walked past and pretended you'd seen nothing untoward.
Maybe some ancient burial grounds might have a vestige of gloom about them...and I rather think that depends on whether or not you happen to have some knowledge of the history before you visit. Here it would be the designated famine graveyards...some areas did have a field or area of ground given over for the burial of the famine victims...though they were usually buried in the town graveyard, if there was the space available...the remoter country areas buried their people in the cillins alongside the suicides and babies and people whose religion wasn't known.
Now, I've written before how there are some actual headstones which leave me cold...I just would rather not touch them if it's all the same to you...there's no rhyme or reason to it...we found a group of stones one day with the skull and cross bones carved into the surface...they didn't bother me one bit.
But actual ghosts rattling chains and moaning piteously? That's just silly.
And now I'll contradict myself yet again...there is a burial ground not far from us which is possibly the nastiest and most disturbing place I've ever been. A plain flat area of land surrounded on all sides by an old stone wall. It's just off the main road and is still being used for burials...it's on the site of one of St Attracta's hospices...nothing of which remains now.
Some of Des's relatives and by default, they are also mine of course...are buried there. We went one sunny summers afternoon to find their graves and honest to god I couldn't wait to leave...there are no ancient headstones...no interesting epitaphs...no-one who was noted for living to a great age...as far as I could tell there were no unbaptised infants at the perimeter nor did there seem to be a designated famine plot...
To use the word 'evil' is maybe rather strong and it isn't a description I'd use lightly...but that place gives off a sense of enormous disquiet...almost as though it doesn't want you roaming about peering at the inscriptions of long dead relatives...it wants you gone.
I'd not ever go back there you know...
Perhaps the Potters Field my detectives were bidden to investigate for clues to the latest murder was like St Attracta's graveyard...perhaps that particular burying ground for the lost and the dispossessed...the people who slept in doorways and those who rode the box cars...people with no names or next of kin...perhaps that burial ground gave off a sense of disquiet that even a Glock in your shoulder holster could not subdue...
