Miss Gosling's Last Case

"We are saddened to report that Miss Winifred Gosling of Marswich Green met her untimely demise this morning in a heartbreaking canine mishap. Miss Gosling, 76, was well-known for her long and illustrious history of crime-solving, and her loss will be keenly felt..."

What utter drivel! It wasn't "a heartbreaking canine mishap", it was arsenious oxide poisoning, and a basic Marsh test would have demonstrated that beyond a shadow of a doubt. But alas. Once again, it seems, you must take it upon yourself to do the constables' job for them, armed only with your wits and your loyal collie--and solve the case of your own murder.
