"An amazing story which has remained untold for far too long. The story of a very brave but also very complex man. This man was my Father and I wish he had been able to explain his life to me in person. However Carolinda has done this exceptionally well." - Robert Dicketts,  5th son of Walter Dicketts aka Double Agent Celery.

The book says it all - no holds barred - a unique and intriguing picture of a profound and perilous risk taker.

The Thirty-Nine Steps." -  Dick Tudhope (Born - Dicketts), 4th son of Walter Dicketts aka Double Agent Celery.
