+Propadienethionyl, HC<sub>3</sub>S, was detected through three consecutive transitions with 13/2 ≤ //J'// ≤ 17/2 between 34.8 and 45.6 GHz in the course of a molecular line survey of the prototypical cold dark molecular cloud TMC-1 carried out with the Yebes 40 m radio telescope. The lines displayed well-resolved Λ-doubling and (reasonably) resolved <sup>1</sup>H hyperfine structure splitting. Some HFS compoents are (essentially) unblended, several slightly or severely. The authors state abundance ratios HCS/HCCS of ~8.1, HCCS/HC<sub>3</sub>S of ~4.5, and HC<sub>3</sub>S/HC<sub>4</sub>S of ~1.6. HC<sub>5</sub>S was evaluated to be near the present sensitivity limit of the survey.\\
