Cohorts 4 is a 114 page comb-bound, letter-sized, two-column zine released in 2002 by IIBNF Press. It contains 20 stories in total, one of which are Holmes/Watson.
The Lion's Den by Violet Nightingale is a 22-page story. This is a first person Holmes account set after the Sign of Four. Holmes thoughts are reported at length, in fact he is internally verbose to a rather implausible extent. Nevertheless is is well written angst in which Holmes pines for Watson and Watson initiates a first encounter and an ongoing relationship is established.
