Used book – The Ivory Dagger, Patricia Wentworth, Claude Bonnafont

The nineteenth investigation of Miss Silver, the cult detective!

Herbert Whitall's room offers a nightmare vision in the early morning: the man was stabbed during the night with an ivory dagger left at the foot of the bed.

Miss Silver admits she is somewhat disoriented. She knows, of course, that Lila Dryden, who was to become his wife, secretly harbored fierce hatred for him; however, this crime could not benefit her. But what about his relatives? With only initial answers and a few meager clues, Miss Silver already suspects that the game will not be easy to play.
