The Crazy Quilt Murders by H.W. Sandberg (Phoenix Press N.Y. 1938)
Rare book (no copies for sale anywhere online) from the Donald Rudd collection of detective fiction. The plot is summarised thus:
When Benjamin Markley willed his nephew Sam a crazy quilt, it seemed like merely one more of his eccentrics on a par with the proviso that Markley legatees spend three days together in Sam's country cabin.
But the Markleys stopped laughing when the three days were blighted by a series of murders more puzzling than any Sam, a mystery writer by profession, had ever imagined. And the colorful crazy quilt enabled Sam to stop the murders before he himself was added to the growing list of victims…
Everything in life must perforce follow a pattern. Life, death, the very thoughts that idle in your brain at this moment, are guided by a logical, if sometimes confusing, pattern. Witness the crazy quilt; modest or gorgeous, seemingly possessing neither rhyme nor reason, yet behold, you find in it a beginning, a body, a conclusion, the very essence of a pattern.( Sam Markley)
