Introduction scenario for Tatters of the King

[CapitalIdea]

I'm planning to run Tatters of the King for a group of friends in early 2017. 

While they are not new to Call of Cthulhu, they are new to 7th Ed, so I am looking at running an introductorary scenario as a bit of a prologue, so that the players can both get used to the new rule set, and introduce their Tatters characters. It will also mean that they have a meaningful connection once Tatters actually start.

So I'm after recommendations for scenarios that aren't too deadly, and that are tonally similar to Tatters. It doesn't matter if they are not 7th Ed scenarios - I'm happy to convert them.

The Sanatorium from Mansions of Madness looks like a natural fit, but I'm worried it jars too much with the slow, creepy build-up of Tatters and might be too deadly (plus the risk of having all those Elder Signs floating around).

Anyone have any thoughts or experiences they wouldn't mind sharing?

To be honest, the campaign's introductory scenario is a remarkably solid start as is - there's minimal risk, but it's also notably weird and does a remarkably good job of driving home how big a deal things are (we ended up with a single character surviving from the performance into Act 2, and she was basically the driving force of the campaign).

Otherwise... a scenario that lets you introduce Estus is useful, or Grahame's brother (who's name escapes me) - I think having a personal tie and opinion of him will help give that first act a little more nuance.
I'd avoid anything dealing with Shub-Nigurath or the Tcho-Tcho, I suspect their chapters works best if the characters and players have as little knowledge of exactly what's going on as possible (or little enough that they're willing to work with them, instead of assuming antagonism). Something involving Chaugnar-Faugn wouldn't hurt - his presence in the campaign always felt a little bit tacked-on, and having the players be familiar enough with him for his appearance to merit a reaction would probably enhance that.

None of which is probably hugely useful, as I can't, off the top of my head, suggest any adventures that fit that criteria!

But good luck either way, I'm a big fan of Tatters - it's a remarkably well written campaign, and I'm more than happy to offer any advice I can from my playthrough
(...like, off the top of my head, be aware when wrapping up Act 1 that the players are entirely within their rights to assume that everyone of importance is now dead, and there's no need to investigate the beginning of Act 2. I think I wrote them an extra letter from Their Friend to prod them into action)

Thanks for those ideas. They are very useful. I need to reread the start of Tatters to see if it does the job.

I am always keen for advice, so your thoughts are more than welcome.  I'll hit you up as things come along.

Have you seen the Yellow Sign from  Tales of the Crescent City book, plus Ripples from Carcosa might have something interesting.

I personally thought Tatters of the King was a convoluted mess. Sure, it starts strong, but then it kind of goes all over the place. It ending with a sadistic choice I also thought was lazy storytelling. The two above books and some of the scenarios for Trail of Cthulhu have some great King In Yellow material.
