[1] Among its negative reviews were from Sam Leith in The Daily Telegraph, who wrote, "And I honestly wish I didn't have to say this, because it feels like kicking a man when he is down... but, really, it's terrible.

[2] John Sutherland, the Northcliffe Professor of English literature at University College London, said "IDS has as much chance of doing a Winston Churchill as Rapper Tony Benn has of going quadruple platinum".

[2] For The Guardian, Peter Preston said, "His prose ranges from lumpen to beserkly lush... the plotting is full of clumsy clotting".

and Widdecombe offering limited praise, calling the novel "scarcely the greatest literature of all time but as a thriller and easy read it will while away a plane journey (or, at 400-plus pages, a couple of plane journeys) perfectly pleasantly...the dialogue is severely cliché-ridden but people do have a habit of talking in clichés".
