I thought about a story i know i read quite awhile ago last night and unfortunately i can't recall the author or title. Clark and Lois are married and
have bought a house. I believe they buy the house
next door from an old lady and sell or give it to
Martha and Jonathan. I think the old lady has accidentally learned Clarks' secret. I seem to remember Martha
baking a lot of pies possibly as a small home based
business. Sound familiar to anyone or am i imagining this one? LOL
Thanks

I believe you're looking for the story:

There's Always Something by Xanabee. Martha and Jonathan buy Bertha Avery's brownstone when Lois gets pregnant. Great story.
