No Man for Murder

I have been looking for this book since 1980. I read it in 7th grade and was fascinated by the relationship btween the boy and the wolf. I HAVE NOT LOCATED IT UNTIL NOW. I WILL READ IT AGAIN TO SEE HOW MUCH I HAVE BEEN ABLE TO RECALL SINCE 7TH GRADE; I DO KNOW IT WAS THE FIRST BOOK OF MY LIFE THAT I READ FROM COVER TO COVER WITHOUT PUTTING IT DOWN! TO THIS DAY, I HAVE A FASCINATION WITH WOLVES AND NATURE AND I AM NOW IN THE FIELD ON CONSERVATION BIOLOGY BECAUSE OF THIS EXACT BOOK! I CAN'T WAIT TO GET A COPY AND READ IT AGAIN AND ADD IT TO MY PRIZE COLLECTION. THANKS FOR HELPING ME LOCATE IT AFTER ALL THESE YEARS!
