"When it's done." He sighs, perhaps realising he's being overly short. "It's a priority, since the Dukes want this mess cleaned up quickly. A day or two at most, I expect."

He points you downstairs and you're escorted by two more Flaming Fists first to the clerks who take detailed notes of your names (such as they are, in "Anri"'s case) and the effects you've lost, before you're finally escorted out of the front door and into Baldur's Gate proper once more. It's still mid morning, and the city is abuzz with activity. The western section of the city has fewer full blown markets as it caters more towards those merchants and offices of a prestigious nature, as well as bordering the unofficially official "noble" district in the northeast. Still, there are some sellers - mostly of the food variety - who serve those who lack private kitchens or simply desire some street food.

While your eclectic group garners a few curious glances, most don't give you the time of day, though the stares of the Flaming Fist soldiers on guard - and the task that lies before you - push you not to linger.

The city is at your beck and call, and it's up to you to determine your approach.

I'm going to go ahead and assume you're not going to want to start any actual infiltration, so instead I'm going to ask the party members to decide - individually - how you're going to be spending the next two days while you wait for your stuff to get found. You don't need to act alone, but nor should you feel the need to stick together.

Some options to prompt you may include, but are not limited to:-
Searching for a specific magical item, either to aid you in your infiltration or just in general.
Observing the Merchant's League building and its comings/goings.
Gathering information (such as on the Merchant's League, the Iron Throne, or something else).
Getting drunk. It won't help (probably), but who knows what might happen?
Searching for people who can train you in specific skills or other areas.
Something else I haven't thought of.

If Sam wants the Hat of Disguise previously discussed, he can spend the first day hunting+buying that for (1d6)[2] * 100gp.

Assume that each day's efforts will require an appropriate ability check - searching for a specific magic item might need a persuasion or perception check, observing the merchant's league might need a stealth or perception check, getting drunk will require an athletics check, etc. etc.

If you can reasonably justify it, I'll accept it and narrate the results.
