That was it – the hush. In Knightly Court, there were interruptions of chatter, meetings along the corridors, the odd joke told in reception, a wheezing splutter from Ludo, the creaking of badly fitting doors. Here, in the open-plan office, there was silence; eyes glued to screens, only occasional murmured questions, overseen by the headmistressy figure of Pamela Bailly. Patrick, now she thought about it, bantered in their own office, not outside it; Sylvia, she suspected, gave up banter a while ago. Morahan himself, however forthcoming with her, was hardly gregarious. In this silence she detected not calmness, but tension.

Her phone sounded – a text. She clicked to view.

A colleague may not be what they seem.

Thought you should know. Take care.

Her heart racing, she checked the number. Not from her contacts. Not familiar. Her fingers burning, she hit reply and typed a single word.

Hello.

She awaited the ping, somehow sure of the worst.

Message sending failed.

Heading north out of King’s Cross, they exchanged idle chitchat before burying themselves behind laptops. Sara forced herself to act naturally with Patrick; the anonymous text preyed on her every waking moment, distorting the lens through which she grabbed occasional glances at him, in touching distance across the table, peering down at his screen.

She tried to convince herself there could be another explanation. It was more than a decade since that last text, sent in precisely the same form of language from an unknown number, had cast its shadow over her life. But people texted all the time, she told herself, without bothering with names. Except, as she well knew, the receiver would know the name from the number – or at least have a number that responded when they checked.

She’d repeatedly gone over the core words: ‘… A colleague may not be what they seem…’ They were too vague to be meaningful. A nothing. Anyone could have made that up.

She needed to stop kidding herself – this was not a random coincidence. Either it was the same sender or someone who knew about, or once had some contact with that sender, and knew their modus operandi. But for what? To scare her? To help her? To undermine her?

She grabbed another look at Patrick, then found herself seeing those other faces in the Inquiry office floating by.

If only she could discuss it with someone. But she understood all too well the logic of her position. The text was a dagger only to her because of the message that July morning fourteen years ago. Unless she owned up to that, anyone looking at this message would simply tell her to ignore it. Some joker trying to wind her up, they’d say. Or the detritus of office politics and rivalries.
