Showing Gaudy Night 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. The twelfth book featuring Lord Peter (the third novel to feature Harriet Vane) is set in an Oxford women's college. With an introduction by Elizabeth George.
Harriet Vane has never dared to return to her old Oxford college. Now, despite her scandalous life, she has been summoned back . . .
At first she thinks her worst fears have been fulfilled, as she encounters obscene graffiti, poison pen letters and a disgusting effigy when she arrives at sedate Shrewsbury College for the 'Gaudy' celebrations.
But soon, Harriet realises that she is not the only target of this murderous malice - and asks Lord Peter Wimsey to help.

'I admire her novels ... she has great fertility of invention, ingenuity and a wonderful eye for detail' P. D. James
