To find a book about sherlock holmes?

i saw this book back in the seventies in a college bookstore. it was about the adventures of sherlock holmes during the martian invasion. a writer combined the idea of sherlock holmes around the turn of the century (1900) and h.g. welles original war of the worlds book of about the same time. does anyone know the author, title, publisher, location of it? ive tried finding it at my librarie; no luck yet.
