Comforts of a Muddy Saturday

In the fabulous new installment in the best-selling adventures of Isabel Dalhousie, Isabel is asked to help a doctor who has been disgraced by allegations of scientific fraud concerning a newly marketed drug. Our ever-curious moral philosopher finds her interest piqued. Would a doctor with a stellar reputation make such a simple but grave mistake? If not, what explains the tragic accident that resulted in the death of a patient? Clearly, an investigation is in order, especially since a man's reputation is in jeopardy. Could he be the victim of someone else's mistake? Or perhaps he has been willfully deceived by a pharmaceutical company with a great deal to gain.
