Renegade cop Sam Batford’s latest undercover assignment puts him between a rock and a hard place… 

An armed gang is robbing cash vans in North London, and DS Batford’s bosses want his help catching them red-handed. 

That’s not all that they want. Convinced he is corrupt, Superintendent Klara Winter is looking to catch him with his hand in the cookie jar. 

But Batford’s immediate danger is being found out by the ruthless mob he has infiltrated. They are packing and not afraid to open fire. 

Used to bending the rules to protect his life, will he use the chance to go clean, or take a step too far and cross the Rubicon? 

LINES CROSSED is the third book in the DS Sam Batford undercover investigations series. 

The first two books, CRIMINAL JUSTICE and STATUS DRIFT, are also available on Kindle Unlimited and in paperback. 

Look out for the author’s four-book Detectives Nash and Moretti crime mystery series, which starts with the novel LATENT DAMAGE!
