Thanks. You might find Carroll's Voice of His Shadow and The Marriage of Sticks TZ-ish, as well.
I've read that Matheson and Beaumont were especially influenced by Ray Bradbury so Something Wicked This Way Comes seems a likely candidate, as would the much later The Shadow Year by Jeffrey Ford and Coraline by Neil Gaiman, both of which seem to reflect the Bradbury. I haven't read it, but I suspect Jack Finney's Time and Again might also be worth looking into for TZ-ishness.
Also the stories by Ray Russel and Manley Wade Wellman , Seabury Quinn
