What is the test for alleging possession of stolen property?

"(P)ossession of stolen property, accompanied by no explanation, or an unsatisfactory explanation of the possession, or by suspicious circumstances, will justify an inference that the goods were received with knowledge that they had been stolen. The rule is generally applied where the accused is found in possession of the articles soon after they were stolen." (People v. Lyons (1958) 50 Cal.2d 245, 258, 324 P.2d 556; to the same effect, see People v. McFarland (1962) 58 Cal.2d 748, 754, 26 Cal.Rptr. 473, 376 P.2d 449.)
