Writing a Blurb

In between telling the various authorities, banks etc where I now live, I have finished the first set of amendments to the Printers Proof copy of Crucial Evidence. The next stage is to write a blurb for the back cover. Trying to condense a 90,000 word novel into 120 is really difficult. Which bit to include, which to leave out. Are the bits I think important the true turning points in the story? This is my first attempt;

Lenny Barker pleads not guilty to a charge of murdering prostitute Shelley Paulson. Cassie Hardman, junior barrister for the defence, believes he is just another defendant trying to avoid responsibility for his crime. Then, just before the trial begins, she discovers he has an alibi. Cassie is determined he will have a fair trial and risks her career to locate the crucial witness.

Will he be found before the jury retire to consider their verdict and will his evidence establish Barker’s innocence? If Barker is not the killer then who is? Can Cassie help Detective Constable Alexis Seymour in her efforts to solve the crime?

Is this enough? I don’t say where the novel is set or that the story follows Barker’s trial at the Old Bailey, which is an important part of the book. I could do to look at the blurb on other books, but all mine are in store at the moment until we get some bookshelves built.
