DUKE VINCENTIO: These letters at fit time deliver me The provost knows our purpose and our plot. The matter being afoot, keep your instruction, And hold you ever to our special drift; Though sometimes you do blench from this to that, As cause doth minister. Go call at Flavius' house, And tell him where I stay: give the like notice To Valentinus, Rowland, and to Crassus, And bid them bring the trumpets to the gate; But send me Flavius first.
