обозначния действия, совершившимуся к моменту речи.

А как быть с действием, которое только что произошло? Можно сказать в момент речи.

Некоторые настаивают на употреблении Present Perfect; но в книге, которую я недавно купила, изложено подробное описание употребления времён глагола, и там написано, что только что случившееся действие употребляется в Past Simple.

Много источников и Интернете пишут, что уместен Pr.S., но и автор книги же явно не дурак.

Помогите, пожалуйста.
