July’s crop of new thrillers are as brutal and scintillating as the summer heat. The following list feels a bit like an ur-list of what crime and mystery novels are—their building blocks, their structure, and above all, their consumption. These novels are variations on a theme, like all good genre fiction; dutiful to those who’ve come before, and paving new paths for those who will follow. In short, July’s new crime releases are a masterclass in, well, crime writing.
