Another young woman sleuthing in London in the aftermath of the Great War. Posie Potter inevitably invites comparison with Jacqueline Winspear's Maisie Dobbs and Gillian Winscott's Nell Bray, and it has to be said that though this is a competently written cosy detective story in the classic early-Agatha-Christie tradition, it is not in the same class as those others I mentioned. Although Posie has been a nurse on the battle field and experienced the horrors of trench warfare at first hand, there is none of the trauma and nightmares here that seemed so right in the Maise Dobbs novels. Nor is the plot comparable to that of, say, the superficially similar Stage Fright by Gillian Winscott. A priceless diamond with a curse on it stolen from a rajah is hardly original.
On the other hand, it was the first in the series, it is very promising, I do like Posie Parker, and I would read another one - and I suppose "cosy" should mean just that, "cosy" - so four stars, yes, instead of the three and a half I had in mind.
