Did you note the commissionaire 's number ? '' `` As it happens I jotted it down , '' said Frank . By this time the manager was on the phone to the police . At seven o'clock that night the commissionaire was discovered . He had been employed , he said , by a Mr. Holland , whom he described as a slimmish man , clean shaven , and by no means answering to the description which Frank had given . `` I have lived for a long time in Australia , '' said the commissionaire , `` and he spoke like an Australian . In fact , when I mentioned certain places I had been to he told me he knew them . ''
