suspenser
n.— «“Mauritius” caters efficiently to a hunger that Broadway hasn’t been gratifying in recent years. That’s the corkscrew-twist drama of suspense, a genre that was a theatrical staple for much of the 20th century.…And “Mauritius” is head and shoulders over recent Broadway examples of what the trade papers like to call suspensers, half-baked plays like John Pielmeier’s “Voices in the Dark” and Stephen Belber’s “Match.”» —“Three Thugs and a Stamp Collection” by Ben Brantley New York Times Oct. 5, 2007.
