We report the results from a 19-hr integration with the SPIRE Fourier
Transform Spectrometer aboard the Herschel Space Observatory which has revealed
the presence of a molecular outflow from the Cosmic Eyelash (SMM J2135-0102,
hereafter SMMJ2135) via the detection of blueshifted OH absorption. Detections
of several fine-structure emission lines indicate low-excitation HII regions
contribute strongly to the CII luminosity in this z = 2.3 ULIRG. The OH
feature suggests a maximum wind velocity of 700 km/s and outflow rate of ~60
Msun/yr. This is lower than the expected escape velocity of the host dark
matter halo, ~1000 km/s. A large fraction of the available molecular gas could
thus be converted into stars via a burst protracted by the resulting gas
fountain, until an AGN-driven outflow can eject the remaining gas.
