Can anyone identify this story? I read it years ago (about 1984-86?) when I had access to a small public library containing mainly old tatty books no longer fit for circulation.
This story was in a sci-fi anthology, but I don't remember what the cover looked like. Possibly Gollancz, they had a lot of those.
The story was either sci-fi or maybe horror, although there was nothing explicitly supernatural or eery about it. In fact I remember it as hilariously funny.
It involved a man (Victorian possibly?) who was examining the journal of a deceased explorer (a relative?). The journal spoke of finding 'something' on his expedition and bringing it back. The 'something' was expressed as a blot n.b. printed as an actual ink blot 💭 in the RL book.
The black 💭 escapes from the journal and runs amok around the room, getting ever bigger (expressed as a bigger ink 💭 in the RL book). The man gives chase but the 💭 eludes him until it gets into another room. When he opens the door to that room the 💭 has completely filled it with blackness... and swallows him up!
I would love to read it again and find out if it was as funny as I remember.
Perhaps the title was something like 'The Blot' (or the 💭)?
