Restrict taxonomy page list to current value

I am trying to provide a set of links for post series using a taxonomy series.

The basics are working, but I can’t get the data selector correct for showing the links in either the page or a widget.

In the page I have a series_list.html partial as follows…

{{ if .Params.series }}
{{ $series := index .Params.series 0 }}
{{ $taxonomy := index .Site.Taxonomies.series $series }}
<section id="menu">
    {{ partial "series_top.html" . }}
    {{ $num := 0 }}
    <ul>
        {{ range $taxonomy.Pages.ByDate }}
        {{ $num = add $num 1 }}
        {{ if eq .Permalink $.Page.Permalink }}
            <li hugo-nav="{{ .RelPermalink}}">Part {{ $num }}: {{ .LinkTitle }}</a></li>
        {{ else }}
            <li hugo-nav="{{ .RelPermalink}}"><a href="{{ .Permalink}}">Part {{ $num }}: {{ .LinkTitle }}</a></li>        
        {{ end }}
        {{ end }}
    </ul>
</section>
{{end}}

and in the current_series.html widget I have

{{ if .Params.series }}
{{ $series := index .Params.series 0 }}
{{ $current := index .Site.Taxonomies.series $series }}
<div class="widget-series widget">
    <h4 class="widget__title">Series: {{ $series }}</h4>
    <div class="widget__content">
        <ul class="widget__list">
            {{ range $current.Pages.ByDate }}
            <li class="widget__item">
                <a class="widget__link" href="{{ .RelPermalink }}">{{ .Title }}</a>
            </li>
            {{ end }}
        </ul>
    </div>    
</div>
{{ end }}

I can make it show all the links to all the series, but can’t restrict it to the current series
