On 5 March 2018, I meet Sergei Skripal for lunch at the Cafe Tatti, in McLean, Virginia.
I ask Sergei about what happened on 4 March 2018.
"I saw a man fiddling with the front door handle, at my house in Salisbury. Then, several hours after I left the house, I began to feel unwell. I don't remember anything after that."
Who was the man fiddling with the door handle?
"Well, he dropped his passport, and I picked it up," explains Sergei.
What was the name in the passport?
