“The wartime double agent is one of the most indelible figures in all of literature. But there are few characters as bizarre and intriguing as the rascal who was codenamed Celery by MI5. In telling the story of her grandfather’s adventures, Carolinda Witt has added a rollicking chapter to our understanding of World War II. And here's the incredible part: It’s all true.” Peter Duffy, bestselling author Double Agent and The Bielski Brothers.

"A classic recipe of wartime espionage with romance, perfidy and tragedy as added ingredients." - Nigel West, bestselling author and intelligence expert. Voted 'The Experts' Expert' by a panel of other spy writers in The Observer in November 1989. "

"An incredible story, a tangled family history and a gripping insight into the murky world of the double agent." - Dr Nick Barratt, author and historian The Forgotten Spy, TV presenter and researcher, Who Do You Think You Are, and Hidden House Histories. 

Firetrench Reviews: "Spy stories, fiction and non-fiction, are enduringly popular. This story of a British agent during WWII will be no exception, with all the elements to keep the reader turning pages to the end – Highly Recommended.

"The author is the granddaughter of agent 'Celery' and has produced an absorbing story of 'Celery' that lifts corners on a grey and murky world. One of the difficulties of the intelligence world is that rarely is anything black and white and the game being played can have many surprising aspects. Little is what it seems and the story of 'Celery' displays some of these traits. It is also a fertile area for conspiracy theory. 'Celery' was intended to be a double agent, but some may suspect that he was a triple agent, whatever proofs are offered to the contrary. Perhaps this is part of the fascination and enthusiasm  for histories and fictions about spies.

"Readers must draw their own conclusions but, whatever they conclude, they will find this a most enjoyable, absorbing and exciting story that is told well and supported by some very interesting images in the photo-plate section." Read full review ...

"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.

My Father would have been very envious and spellbound to see his civilian and wartime exploits so vividly and accurately portrayed by Carolinda Wit. The book says it all - no holds barred - a unique and intriguing picture of a profound and perilous risk taker. There is a strong echo from author John Buchan's all action hero - Richard Hannay - who also had the miraculous knack of getting himself out of sticky situations - viz. The Thirty-Nine Steps." -  Dick Tudhope (Born - Dicketts), 4th son of Walter Dicketts aka Double Agent Celery.
