HARWICH, Mass. -- Police are trying to solve a musical mystery discovered deep in the woods on Cape Cod.

A woman walking in the Bells Neck Woods on Saturday afternoon came upon a piano in perfect working condition, Harwich police said.

The Baldwin piano, which had a matching bench, was set up as if someone was about to sit down and play.

The piano is so heavy that it took more than a half-dozen men to load it onto a truck, police told the Cape Cod Times.

Because the piano had not been damaged, it could not have been pushed out of a vehicle, police said. Someone took great care to place it in the conservation area in superb condition.

Police said they have no idea how the piano came to be there or just how long it had been in the woods.
