The seven sleepers

Pursuing his misdirected luggage to Geneva, Thomas Preston decides to look up Beatrice Harvel, an acquaintance from the war who is working for the League of Nations. While Thomas is killing time in a café, a stranger thrusts a document in his hand and vanishes. Returning to his hotel, he finds a letter instructing him to deliver the document at a meeting with his "grandmother," and Thomas's decision to keep that appointment thrusts him into the middle of a desperate struggle for the future of Europe.
