Lock up these papers: The enemy is vigilant
Three government envelopes labelled Secret, Confidential and Restricted, each marked by a red arrow on a dark ground, under the headline 'Lock up these papers' and the line 'The enemy is vigilant'. The tell for fear-appeal is the unseen watching enemy asserted as the reason to secure documents, with no specific incident shown.
