The Match by Harlan Coben is billed as Wilde #2. I was a smidge confused by this as I could not recall a ‘Wilde’ #1. I then realised I’d missed The Boy From the Woods so came into this without any backstory. And it didn’t matter at all.
Initially I thought it was going to be reminiscent of Linwood Barclay’s Find You First, which featured someone picking off family members with related DNA (discovered through an ancestry match type place). Happily however the DNA matches aren’t really the tipping point here, rather what brings Wilde into the mix.
