Three of the CID were down with flu, and another was in hospital for a minor op. Margolies, whose usual beat was Leith, came highly recommended, which made his new colleagues wary. Sometimes a recommendation was made so a station could offload dead weight elsewhere. But Margolies had proved himself quickly, handling a paedophile inquiry with dedication and tact. Two boys had been interfered with on The Meadows during, of all things, a children’s festival. Darren Rough was already in police files. At twelve, he’d interfered with a neighbour’s son, aged six at the time. He’d had counselling, and spent time in a children’s home. At fifteen, he’d been caught peeping in at windows at the student residences in Pollock Halls. More counselling. Another mark in his police file. The schoolboys’ description of their attacker had taken police to the house Rough shared with his father. At nine in the morning, the father was drunk at the kitchen table. The mother had died the previous summer, which looked to be the last time the house had been cleaned.
