There are some mildly interesting plot hooks in here, but that’s all they are- hooks, there’s no development at all. Five of the entries are interconnected, but these pretty much consist of the investigators showing up to witness the aftermath of events. There might be a few ideas which could be developed by a dedicated keeper, but considering the amount of work which would be required, there are far better resources around out there to use for inspiration.
Just a small point, but I also found the writing to be quite clumsy, with a reliance on stilted dialogue and long words, many of which the author didn’t seem to know the meaning of.
