Dark fantasy series I read in the 90s

Hi everyone! I'm trying to recall the name of a dark fantasy series I read as a teen in the 90s, but I'm pretty sure the books had been around a while at that point. The protagonist in the first book was a male child, and I have very vivid recollections in that book of his being chased by a dark figure on a horse. I recall some sort of time-travel like elements, and at one point he escapes through a hidden door in a fireplace I think. I really thought the series title had the word "Dark" in it, and I feel like "Time" might have also been in there somewhere, maybe as a title word in the book but not the series, but I've been unable to find anything in my google searches. Any suggestions of titles to consider would be appreciated!

Yeah! And that's what I was going to suggest, too. VERY fine series.
