Stephen Leather has again pulled a rabbit out of his hat with this finely crafted story of intrigue and murder.

Andy Bird has left the unit after suffering the after effects of an insurgent attack. It's just him and Tyson, his ex service dog, living rough. His life is placid enough, but things rapidly go south when he witnesses a murder, and the two thugs who commit it try to kill him. Tyson helps him out but he finds himself on the run.

Vanishing into the streets is his preferred oprion, but when he finds that they are tracking his every move, he turns to his old mates for help.

There follows an exciting story of detection, intrigue, and numerous showdowns. The plotting is good, the characters realistic, and the story plausible, and the baddies predictably horrid, and the goodies doing their best in truying circumstances. Good stuff.

A new character bursts upon the scene from Stephen Leather),author of the successful Spider Shepherd series.)

Andy "Birdman" Bird is a former SAS trooper now living on the streets with Tyson his "land shark" who is a Malinois with PTSD.

Whilst sleeping rough behind a skip,he sees a man murdered by Russian thugs. Soon,he is fleeing for his life and using all his old skills and contacts just to survive.

Another great paced book from Leather and hopefully the start of a new series!

I would like to thank McmiIllan Publishing and Netgalley for the opportunity to read this book

Not my normal read but I devoured this one in one sitting. We meet a man and his dog sleeping rough on the streets after an ambush in a missing he not only lost his hearing but also his loved job in the SAS. When he accidentally stumbles on an assassination his whole life is turned upside down when he is being hunted and everyone close to him is in danger and only his old colleagues can help him. Will he get to the bottom of it all before it’s too late. A great thriller and would make a great film.

Stephen Leather is consistently excellent and it was no surprise that this novel followed suit.
I rather like the character of Andy and fell in love with his dog. (Mind you, you would really want to stay on the right side of him!
Solid plot with several twists and, as usual, plenty of (often gory) action to keep us entertained.
Many thanks.

After a mission gone wrong, former SAS soldier Andy Bird finds himself living on the streets with his Belgian Malinois Tyson. But when Bird and Tyson witness a murder, they find themselves pursued across London by a gang - desperate to silence them. Bird has to turn to his former comrades - but just who are they facing and why?

This was a thoroughly enjoyable book and it rattled along narratively. 5*.

A down and out deaf ex SAS soldier and his dog are the unlikely heroes of this cracking well paced thriller. After witnessing a murder in Camden Town and taking on the assailants Andy becomes the hunted by the mystery individuals. They seem able to track him anywhere and after his ex wife is kidnapped he seeks help from his old army comrades. There’s a huge body count as the violence mounts but there’s a satisfactory conclusion and hopefully more to come from Andy and his Land Shark, Tyson.!

I had forgotten what a brilliant author Stephen Leather is. This book had me fully consumed from the first chapter, and I was really hooked, burning the midnight oil until I finished it. The storyline was strong annd excellent . I loved the loyalty between the characters, who never had a moments hesitation to help out a friend. I also loved Tyson, who stuck with Andy through thick and thin. Thoroughly recommend it. Thank you NetGalley for the advanced copy.

If you enjoy action packed thrillers, then this is one for you. It is full of good characters with a believable plot and a brilliant canine character in Tyler. Andy is ex SAS, sleeping rough on the streets of London with his dog and he is a very likeable character. He witnesses a murder and goes on the run with Tyler in a struggle to stay alive. This is an easy 5* from me and I recommend to lovers of thrillers. Thanks to Net Galley for my ARC.

Entertaining, action packed suspense. A down and out character is brought to life and I love his dog. They face assassins together and danger. I flew through this at a steady but fast pace which is how the book environment felt.

Wow! what an absolute blast of a read this is. It’s SO good. I never thought anyone could equal Spider Shepherd but I was wrong. Stephen knocks it out of the park again!
Andy & Tyson are the dream team and I really hope we see more of them and this is the first of a new series.
Be prepared for a rollercoaster ride, SAS, MI5, MI6 GCHQ, but who can you trust?

A long time reader of the Spider Shepherd novels by the same author I've now got a new fave, him names Tyson and he's way cuter than Spider could ever be.

Ex SAS Trooper Andy felt like he'd lost everything when he ended up on the streets, the only thing he'd managed to keep was Tyson, his ex-service dog. Life on the streets wasn't easy and Andy soon learned its all about finding the best place to hide away, but suddenly the best place isn't safe anymore and him and Tyson are on the run.

Good characters, plenty of action and an intriguing plot, this was a great read from start to finish.

My thanks to Pan Macmillan and NetGalley for the early read, all opinions expressed are my own.
