An odd combination?

I'm reading two books at the moment. I often have a fiction and non-fiction on the go at the same time. The Lewis Man by Peter May is Scottish crime fiction, set on the Island of Lewis in the Outer Hebrides. Too Much and Never Enough by Mary L Trump, is a biography of her uncle Donald. There is a link between the two: Donald Trump's mother, Mary McLeod, was born on Lewis. But no-one is blaming Lewis for what has followed!
