The Devil's Brief: A Forbidden Dark Mafia Romance

By Adrian Vale

She was hired to defend the most dangerous man in London.
She was ninety percent sure he did it.
She took the case anyway.

Aoife Brennan doesn't lose. As one of London's sharpest criminal barristers, she has built her career on finding the cracks in the prosecution's case. Not on believing in her clients.

Cillian Maguire doesn't need her to believe in him. He needs her to win.

Charged with murder, the Irish crime lord is everything Aoife knows she should walk away from. Powerful. Ruthless. Impossible to read. But the evidence is thin. The case is wrong. And the man across the consultation table is the most interesting problem she has ever been handed.

As the trial draws closer, the line between professional and forbidden blurs in ways neither of them planned.

She is supposed to prove his innocence.
She is starting to question everything else.
