Only this far. Just the first page:
“Gentlemen,” the Chief Inspector said at last, “I want you to go over every aspect of this case. Since the official record has been my only source of information, I think we should start with a brief summary, Farquart, perhaps you can begin.”
“Certainly, sir, but I don’t know anything about the beginning of the case except what’s in the reports.”
“There were no reports at the very beginning,” commented Gregory somewhat too loudly. Everyone turned to look at him. With exaggerated casualness he began to rummage energetically in his pocket as if looking for a cigarette.
At that moment, I sensed that this ("The Investigation") was a book I had to read.
