What's the Name of That Book??? discussion

I remember reading this series of books back in like 4th grade-ish I believe..but I was an advanced reader so they could be intended for an older audience. Basically there were about a boy who I think lived with his grandparents and befriended an older gentleman who lived across the street. They would solve, well not quite mysteries, but issues of a more sinister nature together. I distinctly remember the covers of the books always scared the crap out of me. They featured long skinny people with super creepy facial features. I remember the books having supernatural type undertones. I know this is really vague, but I have been trying to remember these books for years with no luck. The cover art is still imprinted in my mind after 20 years and I would LOVE to be able to find these books again
THANKS!

The House with a Clock in Its Walls

Maybe the series that starts with that book? It doesn't match completely but your description reminded me of it, so I figured I'd mention it.

K weird...my reply didn't save..long story Short THANK YOU! It wasn't the book you mentioned but the title sounded familiar so I looked up the author and Tada! My years of searching are over. It is the Johnny Dixon series by John Bellairs I was trying to remember. It starts with The Curse of the Blue Figurine in case anyone else is interested. I never would have found it w/o your help! I can't thank you enough!!!

Hi Amy! I never got a notification for this and just now stumbled on this thread ... I'm glad you found what you were looking for. I may have to give it a look myself. :)
