Clapham Wood Wikipedia page – Super short and pointless link, but it’s Wikipedia innit.
Charles Walkers website – At least I think it’s run by Charles Walker. It has a forum and Charles makes appearances now and then to talk about Clapham. Also has details of his other investigations.
Amazon – The Demonic Connection – An expensive resource, but one that has a ton of local history and information on everything spoken about in this episode. Undeniably the source of any writing on the web that details the Clapham mysteries. It goes a little off the deep end, but is worth a read as it’s short and the local folklore and history sections are great. Probably not worth the steep prices, if you can find it cheap (I got mine for a lot less) it’s worth a go.
