After a so-so start, this Spanish thriller series is shaping up nicely in BBC4’s imported-drama slot.

Lawyer Juan Elías, facing a murder charge when his niece Ana goes missing, still claims he can’t remember anything before the night of his car accident, when Ana disappeared.

His actions are plausible, but he previously told his class of students that successful lawyers must be good liars.

Even Elías seems shocked, however, when his wife tells him: ‘Lies are part of every marriage’.
