This lot contains two books by Agatha Christie from the Hercule Poirot mystery series.  Both are vintage hardcovers with mylar covers over their dust jackets, although there appears to have been substantial shelf wear before they were covered.  Both have yellowed, but clean pages.  The titles in this lot include:

• Perilous Journeys of Hercule Poirot: 1938 Book Club edition omnibus contains the titles Death on the Nile; The Mystery of the Blue Train; Murder in Mesopotamia. Spine binding is detached from the hardboard, but interior page bindings are sound; Inked notation on flyleaf;  
• Hercule Poirot's Casebook:  FIRST EDITION; price flap clipped; penciled notation on flyleaf; binding cracked at title page (see picture), but no pages are loose or missing.
