A new homeowner claimed he noticed a crack in his closet while moving in over the weekend and decided to do some sleuthing, suspecting some sort of damage that might need repair.

“Certainly seems like someone did a crappy job putting the floor in this closet,” the homeowner wrote on the photo-sharing site imgur, accompanying a photo of the white floorboard.

Using only a flat head screwdriver, the homeowner easily pried up the board, confirming what he thought was a poor construction job, and pulled the board up further to assess what other damage could be underneath.

Instead of seeing rotten subflooring beneath or another homeowner nightmare, he found something unexpected. A circle with a hole cut into it was embedded in the floor.

“What is this? Should I stick my finger in this hole?” the homeowner, going by CraigNoList, wrote.

Finding he was able to lift up the circle, the homeowner revealed the dial for a safe.

“I don’t have the combo and don’t know what’s inside. Must post to Reddit,” he wrote.

On the social news site, CraigNoList wrote that he contacted several locksmiths, only one of which was able to come look at the lock on Monday. No news yet on what could be inside.

CraigNoList did not immediately respond to TheBlaze’s request for more information.

The moral of the story? As we’ve seen in the past, sometimes it pays to do a little digging behind the walls and beneath the boards of your new home.
