Publisher's Summary

The explosive book from ex-MI5 surveillance officer Tom Marcus takes the listener on a non-stop, adrenaline-fuelled ride as he hunts down those who would do our country harm.

Tom spent years working covertly to stop those who want to do us harm. In his best-selling memoir Soldier Spy, he told how he was recruited and described some of his top-secret operations. In I Spy, he takes us deeper undercover as he puts his life on the line once more. 

I Spy plunges the listener straight into the action as Tom and his team race to prevent terrorists from causing carnage on our streets and outsmart Russian agents, blocking a daring plot that threatens the security of the nation. Relying on their quick wits, training and courage, the extraordinary men and women of MI5 are under intense pressure every day. Not everyone is suited for the work, and Tom shows how the incredibly tough challenges he faced growing up gave him the mental strength and skills to survive in a dangerous world. 

Gritty and eye-opening, this is a unique insight into a hidden war and the sacrifices made by those who fight it. You will never take your safety for granted again. 

This audiobook includes an interview between author, Tom Marcus, and reader, Jason Langley.

Zero Six

Another good book by Tom. Gripping and exciting sometimes while listening I'd realize how I was hanging on every word. Obviously if I can find myself white knuckling it just listening to it it's no wonder he had PTSD. I do recommend his other book soldier spy first but this is a really good follow up.

Even better than his last.

Amazing. You feel like you are right there with them on team as they conduct their operations. Even better than his last!

very insightful - slightly over-performed

really insightful view both of the work that the UK security services do, and of the mental pressures that such work exerts. I wasnt expecting the book to deal with mental health, and to be honest at first I was less interested in this aspect, but as the book progressed this turned out to be extremely interesting. I was surprised, and hooked by the level of detail that 'Tom' went into on the tactics, techniques and procedures - as well as the play-by-play details of each mission... which is far more detailed than anything I've personally seen before... at least for operations that were so recent and still relevant to today's environment. The performance was, in my opinion, slightly over done with too much emphasis delivered on each and every sentence. listening to the epilogue/extra content it's clear that the narrator has a much more relaxed natural voice, which oddly enough is very similar to 'Tom's' - I personally think it would have been better had the narrator taken this more relaxed tone through certain sections of the book, to give a more varied sence of pace and emphasis. Overall though, I loved it. smashed through the book in a couple of car journeys - will definitely listen to again.

Awful

Awfully dull, written by an egotistical maniac and read by a person trying too hard to make it entertaining, which it never will be.

Little of interest and poor narrator

If you're looking for a meaningful insight into MI5, then look elsewhere. This is simply a rather dull narrative of surveillance operations. Hiding in parks and following suspects whilst trying to blend in and not be detected. Hardly groundbreaking stuff. The real details of MI5 ops is obviously secret, that means little detail and lots of padding out with accounts of a troubled childhood, poorly written narrative and scene setting. I found the narrator irritating.

Top read.

A fantastic, thrilling and incredibly honest account of life at the sharp end. Thoroughly enjoyed this, and “ soldier spy “previously. Many of my mates are forces and ex-forces, one of which followed a very similar career path to the author. Making this an even more fascinating read for me, given my mates background. Many thanks to the author for such a fantastic insight into your world. Takes balls to publicly portray your experiences with PTSD. Much respect. Best wishes to you and your family for the future. PS I have also read “protect and kill “ and thoroughly enjoyed it and hope there will be more to follow. All the best. Mark mac.

Melodramatic Rubbish

All a bit cliche and melodramatic. Couldn’t get into it at all. Wouldn’t recommend, unless you like melodrama.

It really is the screams you hear first...

That's how this book starts. The screaming...oh dear the screaming. The writer seems to suffer from an inability to seperate his own experience with those he has made up. It's unclear about the level of artistic licence that has been taken here. Seemingly every experience he has had has included knife edge situation and winner take stakes. The level that the author goes to in terms of self-introspection is astounding...he seems to cultivate an atitidue that he was simulatneously an opressed person and totally in control of his situation irrespective of the surrounding conditions. It is difficult to understand how the stories he writes about could be true. I for one can't believe it...

Mesmerising!

From the opening scene to the end this simply had me in thrall. I'll claim no expertise on how authentic this actually is, after all my knowledge of MI5 is made up of the output of various thriller writers and not much more. However, it feels real, the authenticity promised by an ex-operative seems to be delivered in spades. A big part of the reason for this, it has to be said, is the excellent narration by Jason Langley, he strikes just the right tone and in combination with Marcus's writing it felt possible to imagine being out there as part of a surveillance team, alone in a bar of strangers or flat out in the grass of a Welsh hillside. Just how complete a picture it is we can't tell, after all I am sure that MI5 would take a dim view on too much of their operational procedure being revealed. It is though fascinating and what's more it also provides examples of the toll that this dangerous, highly pressurised work has on those who do it. And thankful we are that they do! If you liked the previous books by this author and want some more then this delivers brilliantly.

If you Read Soilder Spy you'll love this one.

it's a mix of stories which were not in the first book. but also a look into Tom Marcus's background. how he grew up and how he lives during and after MI5. Alot of eye opening tales which show not only the seriousness of national security but how the very people who give the most for our protection, then deal with life after the service. well read and narrated, great book well worth a read.

Absolutely gripping, a fascinating insight...

Having always been fascinated by the "behind the scenes" workings and the unity that everyone works, on all tiers, to ensure national security, I was keen to get the audio book. Perfectly read by Jason and Georgia, this works so well as an audio book, because you feel immersed in the simulated radio transmissions and very much in the moment. I absolutely loved it. Well done to all!!

Please listen

An adrenaline charged account of an MI5 operative, but at what cost to the officers. Good luck 'Tom', thanks to everyone who puts themselves in harms way for others

Very interesting story of modern mi5

I like books based on true people or events so a first hand look into the life of an mi5 counter terrorist agent was very interesting. Like the first book (Soldier Spy), this book tells the story of an agent as he works with his team to keep tabs on home bread terrorists and foreign spies whilst battling his inner demons and the stress of the job. Your kept hooked as the operation heats up. My only gripe with this book (and Soldier Spy too) is the story is regularly interrupted almost like an advert as the author makes yet another sanctimonious speech about how great mi5 is, how they protect the world and risk their lives. All that is certainly true but I don’t need reminding of if every 30 minutes. That aside, the actual story is great. Definitely worth a listen. Very insightful how operatives communicate with each other as they control a target. Despite the small gripe, both books are a good read.
