We first met Carl Houseman in Eleven Days, a magnificient first novel full of Donald Harstad's former occupational insight. The second and third novels were great but lacked a bit of the 'punch' that this, Code Sixty One, definitely doesn't lack.

Donald Harstad writes in a very easy to read style and is ideal for everything from a holiday in the sun to a cold winter's night.
