The Nine O'clock Novella is a first sample of Herminio's written work for the theater. It was first presented in Spanish at the Gershwin Auditorium in Brooklyn College (CUNY) in the spring of 1973. Later, it traveled, in an incipient English version, to the Henry Street Settlement's New Federal Theater (NYC); and in the summer of 1979, to Lincoln Center for the Performing Arts' Out-of-Doors Festival. From there, it travelled to various off-off Broadway settings and to Puerto Rico's Teatro Bellas Artes and the Dominican Republic's Teatro Nacional aside from its presentation in other other states.
