The Dalston Vampire appears in my Haunted Castles book. https://amzn.to/30Os1AB
You can get an edition without sound effects (because I know some people prefer the stories clean) and a copy of the ebook by signing up to my mailing list here:

Sounds are from Ghost Hack and sound effects (including flute) from Freesound.org
