Thanks for your views, Graham. On point , Lily Lloyd acted as you said, but Parry's alibi was given by Mrs Olivia Brine, who stated that Parry was at her house on the night of the murder from 5:30pm til 8:30pm. If this is accepted, Parry could not be the killer, but he could still be involved with the call (see my earlier comment). The police did not adequately verify Brine's statement, however, so a measure of doubt still hangs over Parry.
