noon
The inspector was assisted in his investigation by detectives Michel and Dupation . They interviewed the old couple in charge of the Cité and various neighbours of Doctor Chaleck , but without lighting upon a clue . Nobody had seen or heard anything whatever . Toward noon he and Michel , who did not wish to leave the house , decided to have a modest repast brought to them . M. Dupation , a fidgety official , took this chance of getting away . `` Well , gentlemen , '' he declared , `` you are much more up to this business than I , and besides my wife expects me to luncheon . You do n't need any further help from me ? ''
