Time Traveller

You press the panel inside the time machine and with a lurch and a sick feeling, you are suddenly back in the lab.

The overseer greets you with delight.

"Very well done! Did you get some good pictures? You've only been gone five minutes."

You stare at him. Only five minutes? It was a day in medieval times.

"Yes, I got some great pictures," you tell him. Suddenly, he looks at what you are holding.

"why are you holding a jar of leeches?" He says, sounding a little sick.
