The Thief in the Old Foreman’s Treasure Companion Quest

When the time comes to find the thief in the Old Foreman’s Treasure quest, you’ll be presented with four choices: a cook, a helper, a tailor, and a merchant. You’ll need to talk to each, then deduce the culprit. After speaking to all four, you’re presented with the following conundrum:

• The cook says the helper did it, having seen the helper leave Fersman’s tent with a box.
• The tailor says she didn’t do it, as she was too spaced out to notice much of anything.
• The helper is distraught, claiming he didn’t do it but presenting very little to deflect suspicion.
• The merchant, after a “fee,” says the cook did it.

All of them are shifty in their own way, but the correct answer is the cook. He is a bit too calm, a bit too quick to cast blame, and presents himself as the most upstanding out of a population that seems to be anything but.

Once you pin the cook as the thief, he’ll run to Sampo, where you’ll catch him trying to offload the goods. A fight will ensue when you try to get the analyzer back, but the cook is no boss, just a regular vagrant mook with two small robot buddies.

With the thief taken care of, head back to Natasha’s clinic to finish the quest.
