“Il Coccodrillo” lo chiamano i giornali: perché, come il coccodrillo quando divora i propri figli, piange. E come il coccodrillo è una perfetta macchina di morte: si apposta, osserva, aspetta. E colpisce. Tre giovani, di età e provenienza sociale diverse, vengono trovati morti in tre differenti quartieri, freddati dal colpo di un’unica pistola. L’ispettore Giuseppe Lojacono è l’unico che non si ferma alle apparenze, e riuscirà a trovare il collegamento, apparentemente inesistente, tra i delitti.

Persino a trent’anni da quel giorno, Anna rimarrà per tutti «la forestiera», quella venuta dal Nord, quella diversa, che non va in chiesa, che dice sempre quello che pensa.

Cosí pensa il maresciallo dei carabinieri Pietro Fenoglio, piemontese trapiantato a Bari, che si trova a indagare su un omicidio dove tutto appare troppo chiaro fin dall'inizio. Non fosse che al principale sospettato, su cui si concentra ogni indizio, mancava qualsiasi movente per commettere il delitto.
