I’m reading now Tenant for Death by Cyril Hare and when checking if there are any Cyril Hare’s book translated into Spanish, I came across this collection published by Emecé, Buenos Aires, Argentina, directed by Jorge Luis Borges and Adolfo Bioy Casares. It was a success, 366 detective novels were published between 1945 and 1985. You can find the complete collection here.
I imagine it says a lot about Borges and Bioy Casares’ taste on detective novels.
A Crime is Afoot 
I hope you are enjoying Tenant For Death, José Ignacio. I’ll be interested in what you think of it when you’ve finished.
