His two-volume study entitledAga KhanIII: Selected Speeches and Writings of SirSultan Muhammad Shah, 1902 1955 was published by Kegan Paul International of London in 1998. Dr. Karim Janmohamed, former Head of the 敁珗曄部-ITREB Liaison (now Community Relations) Department at the 敁珗曄部, who collaborated with him for some years in the preparation of the study, recalls the authors meticulous scholarship, a commitment to the highest academic standards and a fluent writing style which are reflected in the 200-page Introduction to the book and the copious annotations to the 229 speeches, writings and interviews that were selected for publication. I also cherish fond memories of his personal warmth and friendship which he always accorded me, says Dr Janmohamed.
