And the face asks the same question the bones have been asking since the Cambridge team found her.

What did they do when she was gone?

The evidence says they placed her carefully.

It says they may have brought flowers.

It says they came back to this spot, with other people, other times, and did it again.

It says they did not simply walk away.

That is not a final answer.

But it is, given what we can know, a significant one.
