Eva Mason was a psychology student. Prior to that she had been convicted of arson in Pennsylvania, but left the state while on parole. As part of her studies, which focused on arsonists and pyromaniacs, she interviewed convicted arsonist Leonard Brooks and became increasingly obsessed with him.

Modus Operandi
Mason copied Brooks' M.O. when starting fires and even picked some of the same addresses. However, she would also set up tripwire traps consisting of balloons filled with triethylaluminium that were stacked on an improvised shelf that would break when firemen broke the tripwire and cause an explosion that would kill the firemen.
Known Victims
Captain Curtis Smith (killed with a tripwire fire trap)
The fire at 152 8th Street in Brooklyn (no fatalities; the fire trap wasn't triggered)
