Observations combined with theoretical modeling of the light curve of therecently discovered supernova 1997D in NGC 1536 suggest that it might host ablack hole formed in the aftermath of the explosion. We consider someobservable consequences of a black hole in SN 1997D and estimate the late--timeaccretion luminosity of the material which falls back onto the hole. We findthat this luminosity, decaying with a characteristic power--law dependence ontime, may emerge above the emission of the envelope in just a few years. Itsdetection would thus provide unmistakable evidence for the presence of a blackhole.Comment: 8 pages, LaTeX, aaspp4.sty style file (AASTEX package), 2 postscript figures (included). To appear in The Astrophysical Journal Letters (scheduled for August 1, 1998 issue, Vol. 502
