I thought I read somewhere the CIA used beryllium for assassinations. It was an interesting read but I can’t find it now...
Is it really that toxic? A quick google search was useless.

ATSDR has some good info on this, mainly a risk from an inhalation exposure scenario.
https://www.atsdr.cdc.gov/ToxProfiles/tp4.pdf
The toxicity of beryllium to the respiratory tract is usually manifested in one of
two syndromes: acute beryllium disease and chronic beryllium disease. Acute beryllium disease is
usually observed at relatively high beryllium exposure levels, has a short period of induction, and is
usually resolved within a couple of months of exposure termination. It is believed to be an inflammatory
response to beryllium and most regions of the respiratory tract are affected; some reported symptoms
include nasopharyngitis, shortness of breath, labored breathing, and chemical pneumonitis.
Two types of dermal effects have been observed in beryllium exposed workers: an
inflammatory reaction and an immune reaction. Edematous papulovesicular dermatitis was observed in
workers exposed to airborne beryllium sulfate, beryllium fluoride, or beryllium oxyfluoride; this is likely
an inflammatory response to beryllium.
