I think the picture of the author (clearly female) is the give-away, but the name "Evelyn" isn't because it is one of those names (e.g. "Lee") that are applied to both men and women.
Though admittedly it belongs to the category: names I'd have thought were exclusively women's except I heard of just this one dude. My list is:
* Evelyn Waugh
* Vivian Richards
* Marion Barry
