This book is for the hard core Lumley fan only.
It has an interview with Brian Lumley, A chronology of events in his life, notes on lumley v lovecraft, A chapter on the necroscope, bibliographys on Brians Novels,collections,short stories and poetery.
A chapter on Demogorgo and Khai is interesting to read, would be worth looking into those books.
So if you are a collector of Brian Lumley books and works this is deff for you otherwise its OK.
If you have all the Necroscope books it does not really tell you anymore about Harry Keogh.
There are also chapters on each necrscope book with a listing of all the people in each book and a note on who they are, what they did. This was a good refresher on whos who in the necroscope world.
It did however get me interestered in some of his other works ie Titus Crow which look like they would be worth reading.
Gave it 3 stars as it does not do a great deal for me.
