sentences:  The duke was the last person to answer calls by the household staff, and raised suspicion almost immediately because, despite the uproar, the windows of his room had remained shut.During searches in rooms adjacent to the duke's, police uncovered the blood-stained handle of a dagger (kept inside in a cabinet), a bathrobe partly washed but still stained with blood, as well as a leather sheath and various items of clothing and paper (all thrown inside a chimney and half-consumed by flames).A more extensive search for the dagger's blade produced no result.
