Tangram is a thriller, a fractured portrait of our contemporary corruption that ranges from the Basque Country to Reykjavík, from London to Calabria. A set of interlinked stories that combines and recombines into a series of possible narratives, each one giving its own perspective on a world built on deceit and damage. A morbidly obese woman, a former actress, imprisons two university students in a basement in Getxo in the north of Spain.

A psychopath decides on Reykjavík as the theatre for his crimes. A thief, recently released from prison, tries to recover the money that he hid years previously on the outskirts of London. A mafioso, recently arrived in a Calabrian village, manages to win the respect of his fellow citizens even as he extorts money from them. A detective struggles to deal with his police duties and a growing sexual obsession.

These stories, apparently separate on the surface, are shown to have far-reaching connections. They are pieces of a puzzle, and it is only on reading the final pages that the last one clicks neatly into place.
