If Eva Dolan's community-corruption puzzles and Dervla McTiernan's calm procedural build appeal, this Portuguese-set crime novel belongs on your list. It favors evidence trails over car chases, uses the Douro as weather and witness, and finds suspense in printers that never cool; readers who enjoy investigative journalism alongside police work will be well served.
The tip lands at 2 a.m. on night-shift reporter Mariana Sanches's desk: a young municipal surveyor, Tomás Vale, claims Barrow Hill—a windswept rise above Afurada, once a Roman tumulus and now an illegal landfill—is being paved into a logistics park to launder bodies and money. He brings a cemetery ledger with two pages cut out, a USB stick of truck GPS traces, and a shaky whisper about an Anglo-Portuguese consortium with friends at City Hall. Mariana passes the evidence to Inspector Ana Meireles of the Polícia Judiciária, and the investigation begins along the damp run of the Douro, past cranes, chapels, and the creak of old barges.
When a young couple is found dead in their Miragaia flat—bathwater cold, a plastic rosary looped on the tap, and river silt in their lungs—it looks like a straightforward call. The tool that crushed their windpipes, a shipyard clamp, sits on the tiles, and the only fingerprints belong to Ângelo dos Remédios, a taciturn undertaker who moonlights hauling waste up to Barrow Hill. Meireles and her team close in, but the neatness stinks of bleach and borrowed alibis.
Salomé Brás, an ex-archives technician with a history of volatile whistleblowing, vanishes the same night the couple dies, leaving only logins to parish-registry software and a trail of scanned burial permits threaded through hacked municipal servers. Her anger has made her a danger to everyone—and the only way she can be reached is through records: baptism ledgers, mortuary tags, a backroom at Agramonte crematorium where the printers never cool. To smoke out a network that hides women and contraband under the cover of funerals, Mariana and Meireles must wade the city's folklore and its paperwork, from the tiled saints of São Bento to midnight on the Dom Luís I Bridge, where Barrow Hill glows like a bruise above the river.
