Portal short story

[Nancy]

Trying to find a science fiction short story ... scientists are studying what appears to be a portal into the idyllic past with a Victorian family. One of the scientists feels irresistibly drawn to this world and goes through the portal. The creatures are not human they attack and eat him and as the story ends they are seen to be figuring out how to come back through the portal to invade Earth.
