I'd read that book, I find the question of what makes us think we've seen a ghost absolutely fascinating. There was a TV show called something like 'Paranormal Home Investigations' where alongside the 'psychic' (as bad as you could imagine) and the 'psychical investigator' who pretty much just went through local records and news to list everyone who'd died within miles of the place and suggest that any or all of them could be haunting it, information clearly passed on to the 'psychic' often on screen, they had a qualified building inspector checking the house out.
The things he found ranged from the obvious, like overgrown trees and squirrels causing scratching sounds, less obvious ones like redundant heating ductwork that could allow voices from outside or next door to penetrate inner rooms and one particularly interesting one where the resident claimed and entity had tried to push her friend down the stairs. The stairs themselves were a spiral staircase that failed building codes on having no handrail and too small treads, it was also slightly too short so whoever installed it had sloped the last few inches of hallway to meet it. Finally, the wall and ceiling of the hallway at the top of the stairs were slightly out of true which had a slightly unbalancing effect as you walked toward the stairs, he described them as a 'death trap', no ghost needed.
Sadly I only saw one short season of it, I suspect the contrast between the woo and the actual investigation that upset the target audience of people that gasp at dust motes.
