True or False – the answer

I was in the office one day when my boss rang. 
Do you know that chap you met this morning is ObL’s brother in law? he asked. 

I wiped the coffee off my laptop and admitted that I didn’t. Then I thought it was a wind up. Almost. But not quite. 

The very British man involved had a half sister who married one of ObL’s brothers in America . The brother later died (ironically) in a plane crash. 

So it is more or less true. I’m not sure whether her being a half sister renders it false but I did do some research, read up on the family and it is a matter of public record. The brother in law is a very amiable and bright man. I hired him and worked with him for a year or so. 

It’s a small world.
