Test of Wills by Charles Todd

I saw a book review for a more recent book in this series but since I like to start at the beginning here it is. Set in 1919, Inspector Ian Rutledge, a British veteran of the Great War secretly still suffering from shell-shock, returns to his Scotland Yard job in hopes of exorcizing his private demons. However, a devious higher-up has learned of his Achilles heel and gets Ian assigned to a potentially explosive and career-damaging case--a murder involving a decorated war hero, a beautiful ward, and a shell-shocked witness. Rutledge is a sympathic character but is suffering from a split personality whom he calls Hamish. We find out midway through the book that he believes Hamish is a ghost that haunts him from the war.

There are many red herrings as up until the end I did not know who the murderer was. But the loose ends are tied neatly except for knowing how Rutledge will handle his own mental issues. Plus Rutledge finds himself wondering if Hamish is a ghost from his past or is he suffering from a split personality. While this was not the most uplifting read I did find myself intrigued by the main characters past and how he is adapting back in his English life. I'm looking forward to reading more in this series.
