I’ll admit this book is hurting my brain somewhat. Probably shouldn’t have started it on a sun lounger but now I’m home I’m wondering if it’s worth persevering with. I keep re-reading passages but I’m not entirely sure I’m following. I mean, I get there’s a mole (not a spoiler) and I know how they found out but a lot of the conversations are going right over my head. Should I cut my losses or will it all make sense in the end??
