The first of the Das Sisters Mystery series finds Inspector Dolly Das of the Singapore CID and her sister, Lily, on the trail of a cold-blooded murder in the Singapore heartlands. On a hazy December night, Mary Jacob's body is found at Silver Springs Condominium. Is it a suicide, or did someone push her out her window? When two more murders occur, pressure mounts on Inspector Dolly Das to solve the case. Supported by her sister, Lily, and their sharp tongued, 78-year-old mother, Uma, Inspector Das hopes to close the case as soon as possible. But can she concentrate when her marriage is breaking up? What will Lily do when she finds herself drawn to one of the suspects? And which Das sister will uncover the crucial clue that will unmask a cool and calculating murderer?
