The Light That Failed

With supplies low, the 4077th gets a truckload of ice cream churns and salt tablets. But what it needs are light bulbs, and in the dimly lit post-op Charles makes an error for which he draws the ultimate wrath of his two surgeon bunkmates. Meanwhile, B.J. receives a mystery novel that everyone in camp reads in turn. The last page is missing and the solution to the mystery is undiscovered until B.J. calls the author by long distance.
