  • BEST PODCAST EVER

    Hello! I just want to say that I feel like it’s hard to combine comedy; a typically more light-hearted category, and true crime; obviously a more dark category, but these two combine it FLAWLESSLY. With Investigator Slater’s beautifully made script and deticated time to research, combined with Tank’s little side comments and jokes, makes this podcast the best podcast I’ve ever tried. Love yall!(Please read my review on the next ep, it would make my day😁)

  • Best podcast out there

    I follow many true crime podcasts but Psychopedia is by far my favourite. I love Slater’s writing and attention to detail on all of her stories. I also enjoy her pop quizzes and feel that they lighten the mood when some of her stories can be dark and heavy. Slater is an incredible writer and her voice is full of energy which just draws you in. Thank you Slater for all the hard work that you do and know that you are loved and appreciated by us all.
