A classic spy thriller by William Keenan

Doris is getting strange telephone calls from someone in Germany trying to reach her boss, Michael Hayward, who is out of the office. When the stranger finally gets hold of Hayward, it’s an old army mate, Dave Owen Thomas, who he hasn't seen in 15 years. Dave sounds very agitated saying that he's in trouble and asks Mike to fly over and help him out. Mike arrives in Germany, but the hotel room David is supposed to be in is occupied by an elderly English gentleman. Early the next morning Michael is awoken by the hotel manager advising that the elderly English gentleman has fallen from an upper floor window - he is still barely alive and is asking for Michael. When Michael arrives, the old man asks him if he reads poetry. When Michael says yes, the old man whispers in his ear so that no-one else can hear: "Late into the night..." before dying. Now, the German police are wondering what Michael has to do with his death?
