Partners in Crime seems to go on US Kindle Countdown once a year or so. It's on US Kindle Countdown again just now, at $1.99 for about 1 3/4 more days before going up to $3.99.
It's a "box set" of five legal thrillers, mostly "first in series":
Rebecca Forster:
Hostile Witness
Paul Levine:
To Speak for the Dead
Scott Pratt:
An Innocent Client
Sheldon Siegel:
Special Circumstances
Pamela Samuels Young:
Buying Time
