Find Parker, Angel, Louis ... and the Collector!

This story comes from a publication requested to the author by a newspaper or as part of a collection of several new, I do not know exactly.
In the preface, Connolly explains his approach, he wanted to get away from the easy and lucrative series of Parker, and try new things like the fantastic (it refers also to "The Book of Things lost "he wrote in this direction and already has a following) that the news had also allowed him to tell a story more quickly, introduce the Collector, to present their first meeting, and to announce a book dedicated to it ...
For fans of Parker so (we find her second pregnancy, I leave you suddenly reintroduce the story in the chronology of the adventures of vigilante detective) others may be lost (it's better to read the books in order, except one where we return to the story of Angel and Louis).
