I just discovered a new great series and bought the previous books as I had a lot of fun in reading this one.
Ethelred and Elsie are two quirky and well thought characters, the claustrophobic atmosphere is very Golden Age and I found this story gripping and entertaining.
Excellent plot and character development, a solid mystery that kept me guessing.
Highly recommended.
Many thanks to the publisher and Netgalley for this ARC, all opinions are mine
