I went to the French Alps, and while I was in Chamonix, I took the day off from skiing to drive to Lac Leman, along the lake, into Switzerland, and back to Chamonix.
When I was in Switzerland, I picked up a hitchhiker. He then wanted out.
A short time later, I picked up another hitchhiker. The second hitchhiker took a film canister that the first one had left in my car???
He said, "I have it" as he got out.
I hardly knew what was happening at the time. I think they used me as a courier without my knowledge. But who is "they"?
