Though I don't think it will help, you may check with the beginning of my story concerning Red Herring Puzzle Club.
It seems like it's been a long time since I tried to enter the R.H.P.C. As you may know, I lost a lot of reputation to find someone able to solve it, and moreover, when I was finally ready to give the answer, the bar I had visited had already been abandoned.
Yet I continued looking for any traces of Red Herring Puzzle Club. After a lot of snooping and sneaking all around the world, I found the bartender who gave me the puzzle in the first place.
-- Oh, Thomas, long time no see. Looks like you're a bit lost. But fear not, because today three suspicious people came to me and warned, that you might come by.
With these words he handed me an envelope.
-- I assure you, my friend, that inside you will find all the answers you will ever need. -- the bartender grinned.
After coming home (I already knew, I was never going to see this man again) I opened the envelope. There were 7 small sheets of paper inside. I have also discovered some diagrams on the outside of the envelope. Here is all of what I have got:
But, unlike the previous puzzle, this looks like nothing familiar. I don't know where to start at all! At least, I have unlimited time now, so I can wait for help all I want :D What is the mysterious message, hidden within these papers?
I should probably apply the transcript of two most informative squares:
piece 6, one way around:
Tight (4)
Lincoln (3)
Speeded (4)
??? (word was smudged beyond recognition) (5)
Twinkle (4)
Panda (2) God (4)
Twins (5)
piece 6, other way around:
Destroy (4)
Greenpeace (4)
Cupid (4)
Abbacy (7)
Superior (4)
Circle (3) Thus (2)
Number (2)
piece 4
up(?):
I will let your door be spun (5)
I'm a letter, not the start, (5)
I'm a smell that you should ban (4)
right(?):
I'm with ocean in part one (6)
I'm before you'd say in Rome (4)
Canoeic palindrome, alas, (5)
down(?):
I'm three less, if upside down (4)
I can swirl, flow, stick and foam (4)
And one of three who might be us (6)
left(?):
I'm a distance you can run (7)
I am therefore from Descartes (4)
I pay taxes to no man (6)
As stated by OmegaCrypton, it's hard to distinguish green colour in the photos. Here is the 7th piece with all black numbers circled:
It looks like the same green ink was used on the cover, for the ticks and for a single dot.
A hint (a week has passed, 2 answers submitted)
A correction I couldn't have made due to the puzzle being on paper:
1) The "ABBACY" hint should technically be "ABBEY" (though I believe these words mean pretty much the same)
2) The "before you say in Rome" hint is completely false; not only I meant 'after', this word doesn't seem to mean even that (yeah); nevertheless, I'm not going to reveal it.
