This series from Syfy is something of a cross between The X-Files and The Librarian, with more of the latter's light touch. We have the usual bickering odd couple, this time from the Secret Service rather than the FBI, coupled with a quirky "boss", who sends them on assignments to retrieve odd, otherworldly artifacts that threaten to Do Bad Things.
In addition to the TV series, SyFy has sponsored a tie-in novel by Greg Cox, Warehouse 13: A Touch of Fever. I've reviewed it here.
