This collection of 50 crime novels was one of the first publications to be launched by El País newspaper, which succeeded in doubling the sales of the newspaper.

The design by Estrada Design always divides the cover in half: a black half alternates with a brightly coloured other half, creating an interesting chromatic separation on the spines.

The illustrations produced by Estrada Design play a prominent role in each cover’s design and are almost always in black and white. The El País Crime Series is one of the most widely distributed book series out of all those published by El País newspaper.
