Showing Strong Poison by Dorothy L. Sayers

The best of the golden age crime writers, praised by all the top modern writers in the field including P. D. James and Ruth Rendell, Dorothy L. Sayers created the immortal Lord Peter Wimsey. His sixth appearance introduces Harriet Vane - the love of his life - and her trial for the murder of her lover. With an introduction by Elizabeth George.
Can Lord Peter Wimsey prove that Harriet Vane is not guilty of murder - or find the real poisoner in time to save her from the gallows?
Impossible, it seems. The Crown's case is watertight. The police are adamant that the right person is on trial. The judge's summing-up is also clear. Harriet Vane is guilty of the killing her lover. And Harriet Vane shall hang.
But the jury disagrees.

'She combined literary prose with powerful suspense, and it takes a rare talent to achieve that. A truly great storyteller.' Minette Walters
