Does this seem credible to you? It is very similar to some of my experiences...

{As we were talking, my phone rang. On the line was an experienced intelligence officer, a professional, whom I had known for several years and who had always been neutral or even benevolent toward my work.

“Do you have more documents?”

“Why do you want to know? Are you too now interrogating me over the phone?” I replied.

“Listen. This is about you. They are interested most of all in whether you have anything more and if you are going to publish more articles. So tell me the truth, because this is a serious matter.”

I sobered up. I knew I had published all information that was important and interesting for the public. So I told him the truth.

“No. I have no documents whose content I haven’t already published.”

“Where are you?”

“Why do you want to know?”

“Because it’s about your safety. Are you alone?”

“I’m in the city with a colleague.”

“Ask him to escort you home. And try to be in the company of other people as much as you can. Spend as little time alone as possible.”

“Why?” What is it that is so serious?”

“Don’t ask questions. Just listen to me and do as I told you.”}
