DOCTOR WHO: Sin Eaters, Volume 4

Don't miss the stunning fourth collection of the Ninth Doctor's all-new comics adventures with Rose Tyler and Captain Jack Harkness!

Two staggering adventures see the Doctor and his companions facing psyche-shattering conspiracies and ancient secrets in equal measure!

First, the Doctor goes undercover at a prisoner rehabilitation facility held within a collapsing singularity - a place where the scientists claim to be able to 'cure' murderers and psychopaths by removing all of their negative emotions. But the Doctor's dark side - and Time Lord physiology - give birth to a horrendously real 'id' that rampages through the station! Has the Doctor's carefree approach to planning finally met a threat that he can't charm or think he way out of?

Meanwhile, Captain Jack has left the TARDIS, and is tracking down more information about his missing years - time and memories he had erased while working as a Time Agent.

When the object of an assassination he was supposedly responsible for turns up alive and well, Jack must delve deep into the past he would rather leave behind, in order to prove worthy of the TARDIS crew...
