Fugitive spy suspect Edward L. Howard has not fled to the Soviet Union and has telephoned his wife from abroad, the Washington Post said, quoting officials in the intelligence community. The sources said the call may indicate that Howard, who has been sighted in Finland, may be uncertain about defecting to Moscow. The FBI has alleged that he made a deal to sell secrets to the Soviets after being fired by the CIA for recreational drug use. He had been a case officer in the CIA clandestine service. Howard fled from his family and job in Santa Fe, N. M., on Sept. 21 when under FBI surveillance.
