The OP asked this exact question on reddit, and someone there stated the Deadly Names was derived from this work.
If that’s the case, yes, be careful OP… there are many friendly Jinn to work with, these ones are not interested in helping you and if you don’t have the skill to contain them they will get revenge for being bothered. It’s not a beginner friendly work.
Yes. You must use the Solomonic Method exactly as described to stay safe.
There was a conversation about it here:
The author of Deadly Names, Shadrach Nineveh withdrew it from publication saying it was a mistake and the Jinn had fooled him, the author of a westernised version of it S Ben Quayin was a BALG author and that went South. If they are anything to go by, and they might not be, then this book might not be the best idea.
There are many other books that have many reviews of success, unless you’re in it for the adventure I’d go with something well tried and true and less controversial to get the job done.
