A Deadly Lesson. Paul Gitsham

don’t really. Waste bins are left outside the door for emptying and sensitive paperwork is taken directly to the communal shredder. About once a month, the cleaners do a quick dust and hoover, but have to be let in to the office to do so. The occupant is expected to either stay in there or ensure that sensitive material is not on display and computers are password locked.’

      ‘Who else is on the list?’ asked Warren.

      ‘The canteen staff were all gone by three-thirty – again, they signed out at reception. The last to leave was the canteen head, who delivered a tray of refreshments to the conference room where the SLT had their meeting. She left it, planning to pick it up the following morning.’

      ‘What time did the reception and admin staff leave?’

      ‘Everyone was out by a few minutes past five. They all either drive or lift-share, so we’re checking them out.’

      ‘What about the rest of the governors? Father Beresford said that none of them attended yesterday’s SLT meeting, however he has no alibi.’

      Sutton consulted his notebook again.

      ‘In addition to Father Beresford, the governing body consists of seven members, including two members of staff who have already been checked out. Of the remaining governors, two have alibis, the rest don’t.’

      ‘Start with those who don’t have an alibi,’ instructed Warren.

      ‘Mick Shorting is a parent governor. He separated from his wife last year. His kids stay three nights a week at their mum’s, and he doesn’t have a new partner. Guess where they were Monday? He works for the post office and does the early shift, so he reckons he was at home from mid-afternoon and in bed by about nine. We’re canvassing his neighbours, to see if anyone saw him.’

      Sutton flicked over to the next page.

      ‘Samantha Maitland is a businesswoman, forty-two years old and married, no kids. No prior ties to the school before joining the board, but she has known Noah Ball for years because she is heavily involved in Catholic education charities. Apparently, she’s training for a marathon and says she was doing circuits of Middlesbury Common yesterday. She reckons it’s safer than running on the roads in the dark. We’ll pull the CCTV from the area to see if we can locate her. Unfortunately, she doesn’t wear one of those GPS fitness trackers.’
