Check package.

The light isn't great, but you can make out that the package is a portrait of the famous mad World War II Nazi, Adolf Hitler. Its brown wrapping paper seems to have done a good job of protecting it from the pool of blood rapidly collecting about a knife wound to the stranger's leg.

In the meantime, fearing that the would-be fare has died, the taxi driver has sped off.

You can:

Take the painting and run like hell back to your hotel.

Bend down and check that the stranger is OK.

Place the against a nearby wall and leave it.

Deliver a swift kick to the stranger's groin. Nazi scum!
