Post-transition metal · element 81

Thallium

Tasteless, odourless, and the poisoner's favourite.

Only 3.5% of people are Thallium. (estimated)

If you're Thallium

You are hard to detect and easy to underestimate. Soft on the outside, quietly dangerous, and best kept at a distance by people who know.

Thallium was the classic undetectable poison until modern tests caught up with it; it's now mostly used in infrared optics.

How to get along with Thallium

Do

  • Keep a respectful distance and enjoy the quiet.
  • Notice what they don't say.
  • Keep things transparent; they detect the rest.

  • Don't underestimate the soft exterior.
  • Don't cross them without knowing what they know.

When it goes wrong: You won't taste it coming. Keep the relationship honest and you'll never need to.
