This is not my favourite book by Eric Ambler, but it’s still really good.

The format is different with the plot being driven via transcribed dictation tape, transcribed tape interview, and narrative reconstruction.

The book is about the Geneva newsletter Intercom. The newsletter was founded by a right-wing American general and is rabidly anti-communist.

Theodore Carter writes the newsletter and, when the general dies, he’s really surprised when a Munich businessman called Arnold Bloch buys Intercom and leaves Carter in charge, as long as he includes short notices from Bloch’s clients in the arms trade.

After visits from the CIA and KGB, Carter begins to realise that Intercom has been publishing military secrets. Carter has also to try and find the writer Charles Latimer who disappeared at Geneva Airport. Can Theodore find out who Arnold Bloch actually is and where he’s based before he has to flee from the people who want him dead?
