There’s no word about how long the car has been parked in the lot. Did the thieves leave it there immediately after the theft? Or, did they return it there to show they still had the works and were serious about a ransom?
There are also indications that the returned van Gogh may in fact be a copy (Ger.) by his friend and homeopathic physician Paul-Ferdinand Gachet. The Weltwoche, a German-language weekly newspaper publiched in Zurich, has investigated these claims in recent years. Gachet’s copies of impressionist works were the subject of a 1999 retrospective at the Met.
