Pisanelli was sweating in his suede jacket. Half-walking, half running, he crossed the quadrangle. Then he caught sight of Trotti.
'Commissario.'
Hs stopped. Surprised, Pisanelli changed direction and came towards the shop. It was a small bookshop within the university precinct that specialized in academic textbooks. It was now closed.
Trotti stood by the shop window, apparently engrossed in the display. Matriarchy in the Po Valley and The Terrorist State were on display. A yellow paperback, The Policeman is Alone.
