Anna takes you through a staff corridor, down one level, into the cold dry air of the restricted stacks. The Defence Intelligence Service collection occupies forty metres of shelving in acid-free boxes, organised by decade.

PROTOKOL-CPH is in box 1973-DIS-0047.

Or it was. The box is there. The folder is there. The folder is empty.

But tucked inside the empty folder, left deliberately — you are certain it was left deliberately — is a business card. No name, no title. Just an address in Hellerup and a time: 23:00.

Tonight.

Anna stands beside you in the stacks. "Someone wanted you to find that card," she says. "Which means they knew you would come here. Which means they have been following your movements."

"Or they know how I think."

"Is that better or worse?"

You turn the card over. On the back, in small precise handwriting: *The original was never here. I have it. Come alone. — L.*

L for Lindqvist.
