Playing With Fire (Skulduggery Pleasant)

With Serpine dead, the world is safe once more. At least, that's what Valkyrie and Skulduggery think, until the notorious Baron Vengeous makes a bloody escape from prison, and dead bodies and vampires start showing up all over Ireland. With Baron Vengeous after the deadly armour of Lord Vile, and pretty much everyone out to kill Valkyrie, the daring detective duo face their biggest challenge yet. But what if the greatest threat to Valkyrie is just a little closer to home...?
