Kate Middleton has been convalescing since mid-January following abdominal surgery. No one has seen her since December 25.

Enough to arouse the concern of fans of the monarchy. Some cite health problems linked to Kate's past pregnancies or a depressive episode. Others imagine a coma, cosmetic surgery, a divorce from Prince William or worse, a tragic disappearance. The princess was seen at a church in Sandrigham for Christmas mass, with William and their three children, George, Charlotte and Louis.
