Stacey Collins is a character portrayed by Monica Staggs in the ABC crime series Castle. Stacey was a matchmaker who, unfortunately, met her maker just before "Nikki Heat" began. Hers is the first body Natalie Rhodes sees while she is shadowing Beckett, in order to soak up the ambiance which will inform her portrayal of Nikki. Stacey therefore engaged the services of an unscrupulous PI, Duke Jones, to catch Bill in flagrante, since said pre-nup included an infidelity clause which would cost him $100 million in settlement to Tonya.
