Introduction

Mr. Alderton gets urgently summoned to Mr. Beckwith's house, where a party has been interrupted by a murder: Mr. James Camden lays crushed between a table and a bookshelf in the study, after a heated argument was moved from the party to the more private room. The detective is not quite happy to work at nighttime, but at least there's already a main suspect, so it should be an easy solve, right?
