All right... I admit it, I'm not great at puzzles. Someone kidnapped my girlfriend, but they left me a ransom message. I obviously don't have a million dollars, and I'm scared.. You seem to know what you're doing, though... can you folks help? The note in question

Please... I need your help.

(The note is the only part of the puzzle. The rest is just for flavor.)

The hidden message in the note reads:

Your girlfriend is safe and sound in the local library.

Thanks to Rubio for transcribing the note. The ...

... message is hidden in the text with a Baconian cipher: 

    WeHAv eYOuR GirLF Riend anDSh eSgoi Ngtob eCoMe thEnE
    Xtbig dEtec tiVec aSEun lesSY oUbri NgusA MillI ondol

Small letters are treated as A, capital letters as B: 
    BaBBa aBBaB BaaBB Baaaa aaBBa aBaaa Baaaa aBaBa aaBaB
    Baaaa aBaaa aaBaa aBBaa aaaBB aBaaa BaaaB BaaaB aaaaa
    aaBaB aaBaa aaaaa aBBaa aaaBB BaaaB aBBaB BaaBB aBBaa
    aaaBB aBaaa aBBaa BaaBa aaBBB aaBaa aBaBa aBBaB aaaBa
    aaaaa aBaBa aBaBa aBaaa aaaaB Baaaa aaaaa Baaaa BaBBa
These five-letter chunks can be decoded with the Baconian cipher, where the null-based positions of the letters in the alphabet are rendered as binary numbers, but with A and B instead of 0 and 1. The variant used here uses a single code for I and J as well as for U and V, so that the alphabet effectively has only 24 letters.

It turns out that the strange I in million isn't special, it's just acapital I. Perhaps it was used, because the capital I of the font looks more like a small ell.

  • $\begingroup$ Aaaah well done. I should have got this, because I pointed the OP to my cipher guide where I used this technique for the Baconian cipher example :P $\endgroup$ – Beastly Gerbil Jun 19 '17 at 8:29
  • $\begingroup$ There is a regular capital I in the text (dollaRs In...), so the special capital I is even weirder. $\endgroup$ – ffao Jun 19 '17 at 8:35
  • $\begingroup$ You got it! @ffao The special one was there so it didn't look like "Milllon" with three Ls. $\endgroup$ – TheThirdMage Jun 19 '17 at 21:36
  • $\begingroup$ but how would a not-so-expert puzzler find this out? ;) $\endgroup$ – Feeds Jul 31 '18 at 10:57

(Very partial answer)

Transcribing the message, including upper/lowercase lettering from the original based on the font lettering shown here, gives:

We HAve YOuR GirLFRiend
anD She'S goiNg to beCome thE
nEXt big dEtectiVe caSE

kNOw YOu're noT An ExperT
PuzZleR thoUGH so We hiD a

MeSsaGe if you cAN read it
comE and gEt HEr.

Note that

the second "I" in MILLION is not actually from the font the rest of the letter is.

I was not able to do anything yet with this information. In particular,

just taking the capitalized letters wasn't helpful by itself, nor ROT-13ed.

Is your girlfriend in

Palestine?

After trying to solve this for minutes, the only thing I came up with was:

The lines under the word "to" led to find this documentary, which takes place in Palestine

    $\begingroup$ Interesting thought process, not the answer I was looking for though. Thanks for pointing that out btw, forgot Word pointed out grammar-y stuff. I'll make an edit. $\endgroup$ – TheThirdMage Jun 19 '17 at 0:02

Is your girlfriend:

Dead?

My explaination:

The " I " in million is replaced with a character very similar to the Chinese symbol for earth i.e. dead and buried

  • $\begingroup$ Also nice logic, neat fact I didn't know! But no, also not really what I was looking for. $\endgroup$ – TheThirdMage Jun 19 '17 at 1:49
  • $\begingroup$ Am I on the right track? (with the symbol that is) $\endgroup$ – user37696 Jun 19 '17 at 1:53
  • $\begingroup$ Sorta. You have the right idea with looking at the words, just not looking in the right ways. $\endgroup$ – TheThirdMage Jun 19 '17 at 1:56
  • $\begingroup$ Also, what is the name of the font? (so I can play with capital letters?) $\endgroup$ – user37696 Jun 19 '17 at 1:56
  • $\begingroup$ Earwig Factory. It's not official; I downloaded it from somewhere because it's the best-looking ransom note-y font I found. $\endgroup$ – TheThirdMage Jun 19 '17 at 2:04

Well I'd say she's

In the Church

Explanation:

Cause It says it right there. And from ZachThePilot's answer, She'd probably be in an underground somewhere there. Go there with some cops :)
