Actually, now I think about it, this has happened before around Christmas/New Year. Parcels went missing at the same time of year. I think it's because the Royal Mail take on lots of temporary staff to cope with the extra Christmas workload (and this time I'm sure it's even worse because of COVID-related staff shortages). And there's always a complement of thieves and incompetents among the temporary staff. Plus the porch-thieves get more active.
