The Day Sanity Was Lost

Castillo's debut arrived with force and built a loyal readership for the Spanish-language thriller. The alternating timeframes are well executed and the premise — the decapitated head with a message — hooks from the first page. It may feel somewhat schematic for demanding readers of Anglo-Saxon thriller, but for those seeking an agile Spanish thriller without high literary pretensions it more than delivers. The first book of a career that has confirmed its proposition.
