Indianapolis PI Albert Samson takes on a hospital, a pharmaceutical company, and the FBI in this "tough and clever" mystery (The New Republic).   After his slowest summer ever, struggling and desperate private eye Albert Samson places an ad in the local paper, offering his services at a bargain price. Instead of new business, he gets an eviction notice.   But his luck seems to change when Dorothea Thomas calls with an unusual tale of woe. Her brother, John, a chemist and pharmaceutical salesman, has been in a coma since a lab explosion seven months ago. Dorothea hasn't been allowed to visit her brother in an experimental wing of the hospital--and she needs Samson to find out why. The case gets him tangled up with the FBI and leads him straight to the black heart of the pharmaceutical industry, where secrets only hide more secrets.   The smart-mouthed midwestern detective who "is always good, wry company" returns in this witty crime novel in the critically acclaimed Albert Samson series (Kirkus Reviews).   The Silent Salesman is the 4th book in the Albert Samson Mysteries, but you may enjoy reading the series in any order.
