In around 1989 I read a non-fiction book about the Toronto, Ontario,
Canada based real estate developers by the name of Reichmann (sp?). 
They owned a company called Olympia and York.  At the time they were
riding a huge wave of success developing and buying office towers in
major cities in North America, and diversifying into other-than real
estate investments such as natural resource companies.  I remember the
title of the book to be something like: "They Reached for an Empire". 
I have tried to locate a copy of this book for 15 years with no
success.  The book is biographical in nature and an excellent read for
those in the real estate business.  I very much want to find a copy
that I can buy.  I have tried ABEBooks and other on-line sites.  I
have asked book sellers and librarians.... all with no success. 
Please help me locate a copy.

Hello.

It sounds like you're describing "The Master Builders: How the
Reichmanns Reached for an Empire" (1986)  by Peter Foster.
