VATICAN CITY – For an institution devoted to eternal light, the Vatican has shown itself to be a master of smokescreens since Pope Benedict XVI's shock resignation announcement.

On Thursday, the Vatican spokesman acknowledged that Benedict hit his head and bled profusely while visiting Mexico in March. Two days earlier the same man acknowledged that Benedict has had a pacemaker for years, and underwent a secret operation to replace its battery three months ago.

And as the Catholic world reeled from shock over the abdication, it soon became clear that Benedict's post-papacy lodgings have been under construction since at least the fall. That in turn put holes in the Holy See's early claims that Benedict kept his decision to himself until he revealed it.
